Description

Module having 32K of static ram organised with dual ports, with read/write access from one port and read only access from the other.

This configuration is useful in the construction of "video ram" for the purposes of creating video output for "home brew" CPU's.

This memory will be used in the VGA video module of the SPAM-1 CPU.

The 32K memory is hopefully sufficient to support a resolution of 160x120 pixels.
