Am91L40, Am9140 Datasheet - AMD

Am91L40 4096 x 1 Static R/W RAM

The Am9140 and Am91 L40 products are high performance, adaptive, low-power, 4k-bit, static, read/write random access memories. They are implemented as 4096 words by 1 bits per word. Only a single +5V power supply is required for normal operation. A DC power-down mode reduces power while retaining da.
