The IS42S8800 and IS42S16400 are high-speed 67, 108,864-bit synchronous dynamic random-access moeories, organized as 2,097,152 x 8 x 4 and 1,048, 576 x 16 x 4 (word x bit x bank), respectively. The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture and clock frequency up to 133MHz for -7. All input and outputs are synchronized with the postive edge of the clock. The synchronous DRAMs are compatible with Low Voltage TTL (LVTTL).These products are pack-aged in 54-pin TSOP-2.
