Alliance Memory Low Power Static Random Access Memory (SRAM) devices are fabricated using high performance, high reliability CMOS technology. Alliance Memory CMOS SRAM devices are designed for low-power applications and are particularly well-suited for battery back-up nonvolatile memory applications. AS6C8008 is a 8,388,608-bit device organized as 1,048,576 words by 8 bits. AS6C1616 is a 16,777,216-bit device organized as 1,048,576 words by 16 bits. AS6C6264A is a 65,536-bit device organized as 8,192 words by 8 bits. AS6C62256 is a 262,144-bit device organized as 32,768 words by 8 bits.
Alliance Memory AS4C Series SDRAM are high-speed CMOS synchronous DRAM containing 64, 128, or 256 Mbits. They are internally configured as 4 Banks of 1M, 2M, or 4M word x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Read and write accesses to the SDRAM are burst oriented; accesses start at selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of a BankActivate command which is then followed by a Read or Write command.
Alliance Memory AS4C Series SDRAM provides for programmable Read or Write burst length of 1, 2, 4, 8, or full page, with a burst termination option. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst sequence. The refresh functions, either Auto or Self Refresh are easy to use. By having a programmable mode register, the system can choose the most suitable modes to maximize its performance. These devices are well suited for applications requiring high memory bandwidth and particularly well suited to high performance PC applications.
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.
Alliance Memory AS7C256A and AS7C4096A are high-performance CMOS Fast Asynchronous SRAM devices designed for memory applications in which fast data access and low power are desired. The Alliance Memory AS7C256A is a 5.0V 262,144-bit device organized as 32,768 words x 8 bits. This fast asynchronous SRAM device is ideal for Pentium™, PowerPC™, and portable computing applications. It provides 5.0V operation without sacrificing performance or operating margins. The Alliance Memory AS7C4096A is a 4,194,304-bit device organized as 524,288 words x 8 bits. This fast asynchronous SRAM device features equal address access and cycle times of 10/12/15/20 ns with output enable access times of 5/6 ns, making it ideal for high-performance applications. These Alliance Memory devices feature chip enable input that permits easy memory expansion with multiple-bank memory systems.
