SIMM
Single In-line Memory Module (SIMM) is a small circuit board with integrated circuit chips used to hold RAM (Random Access Memory). SIMMS clip into the memory expansion socket s on the motherboard.
SIMMs offer two main advantages, minimal consumption of board surface and ease of installation. A vertically mounted SIMM requires very less space when compared to a horizontally mounted DRAM. On a SIMM, the metal leads on either side of the board are electrically tied together.
