The Enhanced Memory Systems 4MB EDRAM SIMM module provides a single memory module solution for the main memory or local memory of fast PCs, workstations, servers, and other high performance systems. Due to its fast 12ns cache row register, the EDRAM memory module supports zero-wait-state burst read operations at up to 50MHz bus rates in a non-interleave configuration and 100MHz bus rates with a two-way interleave configuration.
