IS45S16320D Datasheet | ISSI

OVERVIEW FEATURES - Clock frequency: 200, 166, 143 MHz - Fully synchronous; all signals referenced to a positive clock edge - Internal bank for hiding row access/precharge - Power supply: Vdd/Vddq = 2.3V-3.6V IS42/45Sxxxxx D - Vdd/Vddq = 3.3V IS42/45Rxxxxx D - Vdd/Vddq = 2.5 - LVTTL interface - Programmable burst length - (1, 2, 4, 8, full page) - Programmable burst sequence: Sequential/Interleave ISSI's 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.
