SIMM chips Single in-line memory modules (SIMMs) come in 30-pin and 72-pin variants. The best way to identify a SIMM chip is by a notch next to the contacts on one side.

A technical paper titled “Search-in-Memory (SiM): Reliable, Versatile, and Efficient Data Matching in SSD’s NAND Flash Memory Chip for Data Indexing Acceleration” was published by researchers at TU ...

The SIMM pins only support 32-bit data. Although sufficient on early PCs, the emergence of Synchronous DRAM, or SDRAM, meant that memory modules now required a 64-bit data connection to the ...

Devices therefore contain other, different sorts of chips that work as a memory. That is inefficient, because shuffling data between the two types of chip costs time and energy.
