DESCRIPTION

The IC42S16400A are high-speed 67,108,864-bit syn-

chronous dynamic random-access memories, orga-

nized as 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 166MHz for -6. All input and outputs are

synchronized with the positive edge of the clock.The

synchronous DRAMs are compatible with Low Voltage

TTL (LVTTL).These products are packaged in 54-pin

TSOP-2 and 60ball(64M) VF-BGA.
