At electronica 2016, Alliance Memory will be highlighting its latest high-speed CMOS synchronous DRAMs (SDRAM), including newly released low-power mobile (MSDR), double data rate (DDR), DDR2, mobile low-power DDR2 (LPDDR2), and DDR3 SDRAMs in a variety of densities. The company will also highlight its collaboration with Micron Semiconductor to offer discontinued 512-Mb SDRAMs. In addition, Alliance Memory will be showcasing 16-Mb fast CMOS SRAMs in a wide range of package options.
Alliance Memory’s ICs provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions in industrial, automotive, medical, communications, telecom, and consumer electronics products requiring high memory bandwidth, and they are particularly well-suited to high performance in PC applications. The devices eliminate costly redesigns by providing long-term support for end-of-life (EOL) components. In addition, the company performs minimal or no die shrinks, which frees up engineering resources.
