TC59SM816CFTI-75,-80
TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
4,194,304-WORDS × 4 BANKS × 16-BITS SYNCHRONOUS DYNAMIC RAM
DESCRIPTION
TC59SM816CFTI is a CMOS synchronous dynamic random access memory organized as 4,194,304-words × 4
banks × 16 bits. Fully synchronous operations are referenced to the positive edges of clock input and can transfer
data up to 133M words per second. These devices are controlled by commands setting. Each bank are kept active so
that DRAM core sense amplifiers can be used as a cache. The refresh functions, either Auto Refresh or Self Refresh
are easy to use. By having a programmable Mode Register, the system can choose the most suitable modes which
will maximize its performance. These devices are ideal for main memory in applications such as work-stations.
