High Speed SRAM


High speed SRAM is broadly used in many areas. SRAM as random access memory is the highest fast memory for "Write" or "Read" operating. High speed SRAM can immediately access data as soon as you ask "Read" or "Write" operating at the address.
So you can read or write data of the address in one cycle of the clock. To make faster High speed SRAM need to reduce the clock cycle time and increase the clock latency. Please refer the product list to see more information which have the interaction between cycle time and latency of the clock.
High speed SRAM is mainly used for the Networking appilcation and the cache memory of Server system.

Networking application

Network servers and equipment need blazing fast, efficient buffers. Quadruple/DDR family and NTRAM/SPB synchronous SRAMs offer optimized performance for switches, hubs, routers, and network servers.

Server application

Data servers are shaped by their L3 caches. The faster the cache - the better the server. Synchronous SRAMs are the fastest in the industry enabling peak performance for computing applications.
