Alliance Memory Expands Low-Power SDRAM Portfolio

Offers LPSDR, LPDDR, and LPDDR2 Devices in Wide Range of Densities and Package Options

SAN CARLOS, Calif. — May 8, 2018 — Alliance Memory, a manufacturer of hard-to-find SRAM, DRAM, and SDRAM ICs, today announced that its SDRAM portfolio 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, the company’s 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 minimize 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.

“With the Internet of Things and proliferation of mobile devices in the consumer, industrial, and medical spaces, we’ve committed ourselves over the past few years to solidifying our offering of low-power ICs,” said David Bagby, Alliance Memory president and CEO. “It began with the introduction of our LPSDR SDRAMs in 2014, followed by our LPDDR devices in 2016, and LPDDR2 SDRAMs in 2017. Now we offer a complete low-power portfolio in a wide range of densities and package options to meet the high demand for these parts.”
