GENERAL DESCRIPTION The S2M6408YL and S4M6416YL are high performance dynamic random-access 16MB and 32MB 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 command which is followed by a READ or WRITE command.
