Am91L41
Am91L41 is 4096 x 1 Static R/W RAM manufactured by AMD.
- Part of the Am9141 comparator family.
- Part of the Am9141 comparator family.
DESCRIPTION
The Am9141 and Am91 L41 products are high performance, low-power, 4k-bit, static, read/write random access memories. They are implemented as 4096 words by 1 bit 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 supply voltage as low as 1.5V.
All interface signal levels are identical to TTL specifications, providing good noise immunity and simplified system design. All inputs are purely capacitive MOS loads. The outputs will drive two full TTL loads or more than eight low-power Schottky loads.
Operational cycles are initiated when the Chip Enable clock goes HIGH. When the read or write is plete, Chip Enable goes LOW to preset the memory for the next cycle. Address and Chip Select signals are latched on-chip to simplify system timing. Output data is also latched and is available until the next operating cycle. The WE signal is HIGH for all read operations and is LOW during the Chip Enable time to perform a write.
