Description
The AL4CS211/AL4CS221/AL4CS231/
AL4CS241/AL4CS251 series memory
products are high-performance, low-power
9-bit read/write FIFO (First-In-First-Out)
memory chips. They are specially designed
to buffer high speed streaming data for a
wide range of communication applications,
such as optical disk controllers, Local Area
Networks (LANs), SONET (Synchronous
Optical Network).
