Alliance Memory Low Power SRAM

Alliance Memory Low Power SRAM devices feature a fast access time of 70 ns and low power consumption. The Alliance Memory AS6C1616 is a 16,777,216-bit low power CMOS SRAM organized as 1,048,576 words by 16 bits. The AS6C1616 features a 30mA typical operating current and operates for a single power supply of 2.7V to 3.6V. The Alliance Memory AS6C62256A is a 32,768x8 bit static CMOS SRAM device with read, write, standby, and data retention operating modes. It features a typical operating supply current of 50mA. These SRAM devices are ideally suited for low power applications, including battery back-up nonvolatile memory applications.
