IS42S16400集成电路（IC）的存储器规格书PDF中文资料

OVERVIEW

ISSIs 64Mb Synchronous DRAM IS42S16400 is organized as 1,048,576 bits x 16-bit x 4-bank for improved performance.The synchronous DRAMs achieve high-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input.
