Em614163A-45

The Em614163A-30/35/40/45 is a high speed EDO(Extended Data Output) DRAM organized in 262,144 words by 16 bits. It supports EDO Page Mode and 16-bit data width for high data bandwidth applications. The EDO Page Mode is an accelerated access that provides a shorter page cycle and a faster data access time than the traditional Fast Page Mode.

Compared with Fast Page Mode DRAM, the EDO DRAM data output will be held valid after CAS goes HIGH, as long as RAS and OE are held LOW and WE is held HIGH. This feature allows CAS precharge time to occur without the output data going invalid. Therefore, the EDO CAS timing can be  condensed to carry more data out in a given period.

The Em614163A-30/35/40/45 fully utilizes the EDO Page Mode advantages. It allows 512 random access within a page with a fast cycle time as short as 13.3/15/16/18 ns.

The Em614163A-30/35/40/45 is ideally suitable for high performance graphics frame buffers, CDROMs, disk drivers, set top boxes, and DSP applications.
