DESCRIPTION
TC59SM816BFT/BFTL is a CMOS synchronous dynamic random access memory organized as 4,194,304-words ×
4 banks × 16 bits and TC59SM808BFT/BFTL is organized as 8,388,608 words × 4 banks × 8 bits and The
TC59SM804BFT/BFTL is organized as 16,777,216 words × 4 banks × 4 bits. Fully synchronous operations are
referenced to the positive edges of clock input and can transfer data up to 143M 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.
