DESCRIPTION
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.
