General Description
The A42U2604 is a new generation randomly accessed
memory for graphics, organized in a 4,194,304-word by
4-bit configuration. This product can execute Write and
Read operation via CAS pin.
The A42U2604 offers an accelerated Fast Page Mode
cycle with a feature called Extended Data Out (EDO).
