DIMM RAM times have to be refreshed often in order to retain its contents.
A DIMM (dual in-line memory module) is a double SIMM (single in-line memory module). Like a SIMM, a DIMM is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard.
They are the slots for RAM or Memory. DIMM is the form factor of the memory chips used nowadays (Dual In-line Memory Module like Jakob Kobberholm said below). They differ from laptop memory, which uses SO-DIMM, and older computers, which often use SIMM (Single In-line Memory Module)
DIMM refers to a type of memory module commonly used in desktop PCs, laptops, printers and other devices. ... There are also two notches on each side of the module, these are used to hold the DIMM in place once it is in the slot. In fig 1.2 are two examples of DIMM slots on a motherboard, DDR2 and DDR3.
