IS42S32200L-7BLI-TR

OVERVIEWISSIs 64Mb Synchronous DRAM IS42/45S32200L is organized as 524,288 bits x 32-bit x 4-bank for improved performance.
ThesynchronousDRAMsachievehigh-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input.GENERAL
The 64Mb SDRAM is a high speed CMOS, dynamic random-access memory designed to operate in 3.3V memory systems containing 67,108,864 bits. Internally confgured as a quad-bank DRAM with a synchronous interface. Each 16,777,216-bit bank is organized as 2,048 rows by 256 columns by 32 bits.
