The Am9131 and Am91 L31 products are high performance, low-power, 4k-bit, static, read/write random access memories. They are implemented as 1024 words by 4 bits per word. Only a single +5V power supply is required for normal operation. A DC power-down mode reduces power while retaining data with a .
