IS42S32400B-6T集成电路（IC）的存储器规格书PDF中文资料

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 in 1Meg x 32 bit x 4 Banks.

FEATURES

• Clock frequency: 166, 143, 125, 100 MHz

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

• Internal bank for hiding row access/precharge

• Power supply
