DESCRIPTION
The Am2964B Dynamic Memory Controller (DMC) replaces
a dozen MSI devices by grouping several unique functions.
Two 8-bit latches capture and hold the memory address.
These latches and a clearable,8-bit refresh counter feed
into an 8-bit, 3-input, Schottky speed MUX for output to the
dynamic RAM address lines.
The same silicon chip also includes a special RAS decoder
and DRS buffer. Placing these functions on the same chip
minimizes the time skew between output functions which
would otherwise be separate MSI chips,and therefore
allows a faster memory cycle time by the amount of skew
eliminated.
