OVERVIEW

ISSIs 512Mb 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 512Mb 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
