技术资料 AL422B

The AL422B consists of 3M-bits of DRAM, and is configured as 393,216 words x 8 bit FIFO (first in first out). The interface is very user-friendly since all complicated DRAM operations are already managed by the internal DRAM controller. Current sources of similar memory (field memory) in the market ...
