OVERVIEW

ISSIs 128Mb Synchronous DRAM achieves high-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input.The 128Mb SDRAM is organized as follows.

FEATURES

• Clock frequency: 166, 143, 133 MHz

• Fully synchronous; all signals referenced to a positive clock edge

• Internal bank for hiding row access/precharge

• Power supply
