DDR3 SDRAM FAQs (15)

Can I run Micron’s DDR3 memory at clock speeds slower than 300 MHz?
Yes. Micron supports the optional feature to disable the DLL. This feature allows the DRAM to operate at frequencies slower than 125 MHz. A minimum clock rate is not specified, but the timing still must satisfy the refresh interval (tREFI). When operating in DLL disable mode, special conditions apply: - no support of on-die termination (ODT); ODT must be disabled or turned off - both CL and CWL must be equal to 6 - data out is no longer edge-aligned to the clock and read latency will be AL + CL - 1 tCK
How do I determine my CAS WRITE latency (CWL)?
In DDR3, only one CWL is valid for a given clock frequency range. - tCKavg = 2.5ns to <3.3ns, CWL = 5 - tCKavg = 1.875ns to <2.5ns, CWL = 6 - tCKavg = 1.5ns to <1.875ns, CWL = 7 - tCKavg = 1.25ns to <1.5ns, CWL = 8
How do I determine the amount of time between ZQCS commands?
Each ZQCS command can correct a minimum of 0.5 percent impedance error within 64 clocks. To calculate the ZQCS interval, use the following formula: ZQCS Interval =ZQCorrection (Tsens x Tdriftrate) + (VSens x Vdriftrate) For the sensitivities, use the MAX number from the ODT voltage and temperature sensitivity table in the component specification. Drift rates will vary from system to system. ZQCorrection equals 0.5%/64 clocks.
What component densities are available?
JEDEC has defined DDR3 densities of 512Mb–8Gb; Micron plans to support 1Gb through 4Gb.
What is burst chop?
Due to DDR3's use of the 8n-prefetch architecture, a true burst of 4 is not possible with most designs. Burst chop mode (BC4) is unique to DDR3. In this mode, the last 4 bits of the burst are essentially masked. Timing in BC4 cannot be treated like a true BL4. For READ-to-WRITE, select WRITE-to-READ, and select WRITE-to-PRECHARGE transitions, the system can achieve clock savings in the BC4 mode. While doing READ-to-READ or WRITE-to-WRITE transitions, timing must be treated like BL8; no clock savings will be realized.
What is Dynamic ODT?
Dynamic ODT (Rtt_WR) enables the DRAM to change termination values during a WRITE without having to perform a MODE REGISTER SET command. When Rtt_Wr and Rtt_Nom are both enabled, the DRAM will change termination values from Rtt_Nom to Rtt_Wr at the beginning of the WRITE burst. Once the burst is complete, the termination will be changed back to the Rtt_Nom value. Rtt_Wr can be used independently of Rtt_Nom, but termination will be on WRITEs only.
What is the difference between the ZQCL and ZQCS commands?
ZQCL stands for ZQ calibration long. This command must be issued during the power-up and initialization sequence and requires 512 clocks to complete. After power-up and initialization, the command can be issued any time the DRAM is idle. These subsequent commands only require 246 clocks. This command is used when there is more impedance error correction required than a ZQCS can provide. ZQCS stands for ZQ calibration short. This command can be performed any time the DRAM is idle. One ZQCS can correct a minimum of 0.5 percent impedance error and requires 64 clocks.
What is the "MPR"?
MPR is a multi-purpose register. It is a specialized register designed to allow predefined data to be read out of the DRAM. Data is one bit wide and is output on a prime DQ. For Micron DDR3 parts, the prime DQs are DQ0 for x4/x8 and DQ0/DQ8 for x16. Two locations in the MPR are defined. One allows the readout of predefined data burst—in this case, 01010101. The other location is used to output the refresh trip points from the on-die thermal sensor.
What is the operating voltage?
DDR3 operates at Vdd = VddQ = 1.5V ±0.075V.
What is the output driver impedance for DDR3?
The default output driver impedance for DDR3 is 34 ohms. The impedance is based on calibration to the external 240 ohm resistor, RZQ.
What is the RESET# pin used for?
RESET# is the master reset for the DRAM. It is an active LOW, asynchronous input. When the RESET# is asserted, the DRAM outputs and ODT will tri-state. The DRAM counters, registers, and data will be unknown. A RESET must be performed as part of the power-up and initialization sequence. During this sequence, the RESET# must remain LOW for a minimum of 200µs. After power-up and initialization, RESET# may be asserted at any time. Once asserted, it must stay LOW for a minimum of 100ns and a full initialization of the part must be performed afterward.
What is "write leveling"?
For improved signaling, DDR3 modules have adopted fly-by technology for the commands, addresses, control signals, and clocks. Due to signal routing, this technology has an inherent timing skew between the clock and DQ bus at the DRAM. Write leveling is a way for the system controller to de-skew the DQ strobe (DQS) to clock relationship at the DRAM. A simple feedback feature provided by the DRAM allows the controller to detect the amount of skew and adjust accordingly.
What is "ZQ Calibration"?
The ZQ calibration command can calibrate the DRAM's output drivers (Ron) and ODT values (Rtt) over process, voltage, and temperature when a dedicated 240 ohm (±1 percent) resistor is connected from the DRAM's ZQ pin to ground. In DDR3, two different calibration commands exist: ZQ calibration long (ZQCL) and ZQ calibration short (ZQCS). ZQCL is normally used during power-up initialization and reset sequences, but may be issued at any time by the controller, depending on the system environment. ZQCS is used to perform periodic calibrations to account for small voltage and temperature variations; it requires a smaller timing window to complete.
Will Micron support an extended temperature range for DDR3?
Yes. Micron DDR3 parts will support a Tcase of 0°C to 95°C.
Are the DDR3 voltages backward compatible?

Yes, all of our 1.35V parts are backward compatible with 1.5V.

DRAM FAQs (8)

Can CKE be tied HIGH throughout SDRAM operation (initialization and normal operation)?
JEDEC does not specify the exact state of CKE during initialization; it is supplier specific. Micron strongly recommends CKE be kept at an LVTTL logic LOW before applying a stable CLK signal. During normal operation, CKE can be tied HIGH. The initial LOW state of CKE prevents parts from receiving an illegal LMR command, which could put the part into an unknown or unexpected state.
Can the SDRAM clock frequency be changed?
Micron SDRAM data sheets require that the clock frequency be constant during access or precharge states (READ, WRITE, tWR, and PRECHARGE commands). At other times frequency should not matter much because there is no DLL in SDRAM however, we do not recommend it. Lowering SDRAM frequency is OK even if you are not doing an LMR and CAS latency change. In case of increasing frequency, ensure tCK and CAS latency specifications are met. In either case, all other data sheet timing specifications should be adhered to.
Is there a recommended lowest working frequency for SDRAM?
Because SDRAM does not have a DLL, there is no recommended lowest frequency. SDRAM parts will work at very low frequencies if all data sheet specifications are met. It is important to maintain a good slew rate, however, since a very slow slew rate will affect setup and hold-time transitions. Also, for operating frequencies of 45 MHz, tCKS = 3.0ns. For more information, see TN-48-09.
What is a "bank"?
A bank is an array of memory bits. Multiple arrays or banks are contained within a DRAM component. Depending on density, DRAM components may consist of 4 or 8 banks. For example, a bank may consist of 32 million rows, 4 bits across. This would equate to 128 megabits. Four of these banks in a single DRAM component would yield a 512Mb component.
What is the impedance tolerance of the driver in match-impedance mode relative to the expected value base on the perfect reference resistor connected to ZQ pin?
The impedance tolerance of the driver is ±15 percent.
Does thermal information change for IT parts?
Thermal information includes temperature limits and thermal impedance values. Temperature limits do change for IT parts (TC, TJ, and TA), but thermal impedance values (θJA, θJB, and θJC) do not because thermal impedance depends primarily on the package.
My design was based on a specification stating the JTAG was relative to VDD (1.8V), but now we’ve discovered that JTAG is actually relative to VDDQ (1.5V). It’s a fairly significant board spin to change this; what do I risk by leaving the design as-is? I assume that the specification is still for VDDQ + 0.3V = 1.8V, but with CMOS parts there’s no way I can guarantee that it won’t swing past that on transitions.
Your particular board design should not be a cause of major concern. The pins can handle the VDD voltage regardless of the VDDQ voltage.
Should the ECC memory chip share chip select and CKE signals with the other two main memory chips in our point-to-point application?
The ECC chip(s) should share the same CKE and CS# as the other devices because they are accessed as the same piece of data.
