All inputs and outputs are synchronized with the positive edge of the clock . The 64Mb SDRAM uses synchronized pipelined architecture to achieve high speed data transfer rates and is designed to operate in 3.3V low power memory system. It also provides auto refresh with power saving / down mode. All inputs and outputs voltage levels are compatible with LVTTL . Features Fully synchronous to positive clock edge Single 3.3V +/- 0.3V power supply ……
