Improving Ultrathin Boot Performance with Quad I/O

By Redge Villanueva - 2013-01-02

In today’s fast-paced world, consumers need faster system boot times in their ultrathin devices. But other advanced system features, like security, can interfere with boot-time performance targets, posing a challenge to ultrathin designers. The new quad I/O feature in Micron’s N25Q SPI NOR Flash memory can help. N25Q SPI NOR is the first in the market to support quad I/O mode at a 108 MHz clock rate, reaching read transfer rates up to 54 MB/s and improving read bandwidth up to 85% compared to single I/O reads at 50 MHz.

Implementing the N25Q quad I/O feature of x1 instruction/ x4 address/x4 data is easy—designers simply issue the quad I/O commands (such as EBh opcode)—you don’t even need to configure the device. Our advanced N25Q device also supports basic functionality such as single or dual I/O reads, allowing systems to do slower read operations according the needs of the ultrathin application.

Available in 32Mb, 64Mb, 128Mb, and up to 1Gb densities, quad I/O-equipped N25Q SPI NOR is quickly becoming the technology of choice for the ultrathin market, including Intel Ultrabooks™ and AMD ultrathin laptops.
