Alliance Memory, a manufacturer of hard-to-find SRAM, DRAM, and SDRAM ICs, has expanded its SDRAM portfolio which now features a wide variety of components that combine low power consumption with power-saving features to extend battery life in mobile devices.

Alliance Memory's lineup of high-speed CMOS mobile low-power SDRAMs includes SDR (LPSDR), double data rate (LPDDR), and DDR2 (LPDDR2) devices.

Featuring power consumption of 1.8V, its LPSDR SDRAMs are available in densities of 128Mb, 256Mb, and 512Mb in 54-ball and 90-ball FBGA packages.

LPDDR devices feature power consumption from 1.7V to 1.95V and densities of 256Mb, 512Mb, 1Gb, and 2Gb in the 60-ball and 90-ball FBGA packages.

Enabling ultra-slim designs, LPDDR2 SDRAMs offer power consumption of 1.2V/1.8V and densities of 1Gb, 2Gb, and 4Gb in the 134-ball FBGA package.

For designers of mobile devices tasked with providing more functionality in tighter spaces while using less power, Alliance Memory's low-power SDRAMs offer a variety of power-saving features, including auto temperature-compensated self-refresh (TCSR) to minimise power consumption at lower ambient temperatures.

In addition, their partial-array self-refresh (PASR) feature reduces power by only refreshing critical data, while a deep power down (DPD) mode provides an ultra-low power state when data retention isn't required.
