SIMM Sockets

SIMM (Single In Line Memory Module) sockets are computer memory expansion holders that connect memory modules to circuit boards. These sockets have single row pins which connect to the system board vertically or at predetermined angles. The sockets are easily inserted or extracted because they are not soldered onto the circuit board.

SIMM sockets have positive polarisation to prevent the memory modules from being inserted incorrectly. Contacts (pins) on the SIMM sockets have anti-overstress features and are resistant to high temperatures.

What are SIMM sockets used for?

The main benefits of using SIMM sockets are their space-saving capabilities and simple installation mechanisms, making them suitable for smaller circuit board designs used by electronic hobbyists. SIMM sockets are legacy components, mainly used in older module computers, PCBs and motherboards

Types of SIMM sockets

SIMM sockets come in various sizes and are distinguished by the number of pin slots:

  • 30-pin SIMM sockets are shorter than standard sockets and can be used in legacy type laptops.
  • 64- and 72-pin SIMM sockets are used in desktop motherboards because they can hold larger memory modules.
