In this project
The 684000 is a 4,194,304-bit high-speed Static Random Access Memory organized as 524, 288 words by 8 bits. The device is fabricated using Samsung's advanced CMOS process. The 684000 has an output enable input for precise control of the data outputs also has a chip enable inputs for the minimum current power-down mode The 684000 has been designed for high speed and low power applications. It is particularly well suited for battery backup non-volatile memory applications.
