  • Switched memory module
    Patent number: 4882700
    Abstract: A printed circuit board is designed to conform to a single in-line memory module (SIMM) configuration, but includes multiple rows of the memory devices. By controlling a sequence of enable signals, selection of a single row from the multiple row of memory devices can be accomplished. The ability to address the different rows multiplies the memory capacity of the board by the number of rows of memory devices.
