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.
