| Dual In-line Memory Module (DIMM) is a type of computer memory that is natively 64 bits, enabling fast data transfer. DIMM is a module that contains one or several [[dido:public:ra:xapend:xapend.a_glossary:r:computermemory]] chips on a small circuit board with pins that connect it to the computer motherboard. The DIMM stores each data bit in a separate memory cell. DIMMs use a 64-bit data path, since processors used in personal computers have a 64-bit data width. DIMMs are typically used in desktop PCs, laptops, printers and other devices. | Dual In-line Memory Module (DIMM) is a type of computer memory that is natively 64 bits, enabling fast data transfer.

| - | A SIMM (single in-line memory module) typically has a 32 data bit (36 bits counting parity bits) path to the computer that requires a 72-pin connector. For [[dido:public:ra:xapend:xapend.a_glossary:s:sram]] chips, which have a 64 data bit connection to the computer, SIMMs must be installed in in-line pairs, since each one supports a 32-bit path. A single DIMM can be used instead. Originally, a DIMM had a 168-pin connector to support 64-bit data transfer. | + | A [[dido:public:ra:xapend:xapend.a_glossary:s:simm]] typically has a 32 data bit (36 bits counting parity bits) path to the computer that requires a 72-pin connector.

| As faster [[dido:public:ra:xapend:xapend.a_glossary:d:dram]] was developed, DIMM circuit boards evolved. Modern DIMMs based on double data rate fourth generation (DDR4) SDRAM chips use 288-pin connectors to attach to the computer motherboard to enable the increase in data throughput. As clock speeds of the RAM chips increased, the 64-bit path handled increasing amounts of data. | As faster [[dido:public:ra:xapend:xapend.a_glossary:d:dram]] was developed, DIMM circuit boards evolved.
