CellularRAM® Memory Boosts Mobile Performance and Value
CellularRAM memory is a pseudo-static DRAM (PSRAM) device that features an SRAM-like architecture, hidden refresh operation, and SRAM pin-compatibility. This hybrid memory delivers the best of SRAM and DRAM features, combining low power consumption and high-speed READ and WRITE functions. It’s an ideal solution for low-power, space-limited mobile designs and MCPs.

Burst A/D MUX Memory for Cost-Sensitive Mobile Markets
Reliable, low-density, and low-pin-count Burst A/D MUX CellularRAM die are excellent solutions for low-cost, entry-level phone designs. Several technical notes are available to help you understand this memory type and decide whether Burst A/D MUX CellularRAM memory is right for your design.

Because PSRAM/CellularRAM memory offers higher frequencies, synchronous operations, fast access, and variable latency initial burst access, you get high throughput and excellent performance.
Our CellularRAM memory is compatible with the standard wireless Flash interface and it's easy to use in an MCP with burst Flash memory, saving you design time.
Micron tests rigorously across the temperature range at wafer sort to ensure that the quality/reliability of our die is the best in the industry. Also, Micron's implementation with 2T architecture and 6F² cell size provides very low power in the same die size. PSRAM/CellularRAM devices offer several power-saving features like PAR, TCR, and DPD to save power and extend battery life.

Key Features
Our PSRAM/CellularRAM memory is designed several unique features that fit well with the requirements of mobile applications.
Variable Latency
Cuts access time in half, making first data available as quickly as 35ns.
Fixed Latency
Enables compatibility with older systems.
Adjustable Output Drive
Enables users to tune outputs to match system impedance and minimize noise and power.
Partial-Array Refresh (PAR)
Reduces standby current by refreshing only that part of the memory array required by the host system.
On-Board Temperature Sensor
Reduces standby current by automatically adjusting the refresh rate according to the operating temperature of the device.
Deep Power-Down (DPD)
Disables all refresh-related activity to reduce current consumption if the system does not require the storage provided by the PSRAM device.
