The AL422B consists of 3Mbits of memory,

and is configured as 393,216 words x 8 bit

FIFO (first in first out). The built-in address

and

pointer

control

circuits

provide

straightforward

bus

interface

serially

read/write memory that can reduce inter-chip

design efforts. The 8-bit read/write ports can

operate independently at a maximum speed of

50Mhz.

Current sources of similar memory (field

memory) in the market provide limited

memory size which is only enough for holding

a TV field, but not enough for a whole PC

video frame which normally contains 640x480

or 720x480 bytes.

The AverLogic AL422

provides 50% more memory to support high

resolution for digital PC graphic or video

applications. The 50% increase in speed also

expands the range of applications.
