GENERAL DESCRIPTION The S4M644YL and S8M648YL are high performance dynamic random-access 32MB and 64MB modules respectively. These modules are organized in a x64 configuration, and utilize dual bank architecture with a synchronous interface. All signals are registered on the positive edge of the clock signals CK0 through CK3. Read and write accesses to the SDRAM are burst oriented; accesses start at a location and continue for a programmed number of locations in a sequence. Accesses begin with an ACTIVE mand, which is followed by a READ or WRITE...
