ISSI, Integrated Silicon Solution Inc IS42S32800D-7TLI

Description
The IS42S32800DIS45S32800D8M is a 256Mb Synchronous DRAM (SDRAM) organized in 2Meg x 32 bit x 4 Banks. It operates at clock frequencies of 166 and 143 MHz and features a fully synchronous design with all signals referenced to a positive clock edge. The SDRAM incorporates an internal bank to hide row access and precharge operations, enhancing performance.
