Low-Power SDRAMs in a Wide Range of Densities and Package Options

The News: Alliance Memory’s 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.

Part Numbers: Please see table below.

Availability:Samples and production quantities of Alliance Memory’s SDR (LPSDR), double data rate (LPDDR), and DDR2 (LPDDR2) devices are available now, with lead times of four to six weeks.

Key Specifications and Benefits:

  • SDR (LPSDR) SDRAMs
    • Power consumption of 1.8V
    • Densities of 128Mb, 256Mb, and 512Mb
    • x16 and x32 organizations
    • 54-ball and 90-ball FBGA packages
  • DDR (LPDDR) SDRAMs
    • Power consumption from 1.7V to 1.95V
    • Densities of 256Mb, 512Mb, 1Gb, and 2Gb
    • x16 and x32 organizations
    • 60-ball and 90-ball FBGA packages
  • DDR2 (LPDDR2) SDRAMs
    • Enable ultra-slim designs
    • Power consumption of 1.2V/1.8V
    • Densities of 1Gb, 2Gb, and 4Gb
    • x16 and x32 organizations
    • 134-ball FBGA package
  • Power-saving features:
    • Auto temperature-compensated self-refresh (TCSR) to minimize power consumption at lower ambient temperatures
    • Partial-array self-refresh (PASR) feature reduces power by only refreshing critical data
    • Deep power down (DPD) mode provides an ultra-low power state when data retention isn’t required

Target Applications:

  • Internet of Things and consumer, industrial, and medical mobile devices

The Context:With the Internet of Things and proliferation of mobile devices in the consumer, industrial, and medical spaces, Alliance Memory has made a commitment over the last few years to solidify its offering of low-power ICs. It began with the introduction of the company’s LPSDR SDRAMs in 2014, followed by its LPDDR devices in 2016, and LPDDR2 SDRAMs in 2017. Now Alliance Memory offers a complete low-power portfolio in a wide range of densities and package options to meet the high demand for these parts.
