IC Memory Definitions
The list below contains some common definitions for memory module abbreviations, and or integrated circuit memory types. The links directly above are concerned with general electrical engineering, covering many topics. A separate link below the table covers only abbreviations used with memory modules.

| CAM: | Contact Addressable Memory |
| BEDO: | Burst EDO |
| DDR: | Double Data Rate [See Memory Module Definitions] |
| DIMM: | Dual In-Line Memory Module. [See Memory Module Definitions] |
| DRAM: | Dynamic Random Access Memory (Requires Refresh) |
| DRSL: | Differential Rambus Signaling Levels |
| EDO: | Extended Data Out |
| eDRAM: | Embedded DRAM |
| EEPROM: | Electrically Erasable PROM |
| EPROM: | Erasable PROM |
| ESDRAM: | Enhanced SDRAM |
| FCRAM: | Fast Cycle Random Access Memory |
| FRAM: | Ferroelectric RAM (non-volatile RAM) |
| FPM: | Fast Page Mode |
| MDDR: | Mobile DDR |
| NVRAM: | Non-Volatile RAM |
| nvSRAM: | combination of SRAM and EEPROM [also called nvRAM] |
| PBRAM: | Pipelined Burst RAM |
| PROM: | Programmable Read Only Memory |
| PSRAM | pseudo-SRAM |
| RDRAM: | Rambus DRAM |
| RLDRAM: | Reduced Latency DRAM |
| QBM2 | Quad Band Memory, DDR Compatible at increased speed |
| QDRII: | Quad Data Rate [also called DDR2, DDRII, QDRSRAM, and QDR-2 SRAM] |
| RDIMM | Registered DIMM [See Memory Module Definitions] |
| RLDRAM: | Reduced Latency DRAM |
| SIMM: | Single In-Line Memory Module. [See Memory Module Definitions] |
| SODIMM: | Small Outline Dual In-Line Memory Module [See Memory Module Definitions] |
| SDRAM: | Synchronous DRAM |
| SDR DRAM: | Single Data Rate SDRAM |
| SGRAM: | Synchronous Graphic RAM |
| SLDRAM: | Synchronous-Link DRAM |
| SRAM: | Static Memory (Faster than DRAM, but more expensive) |
| TCAM: | Ternary CAM (High, Low and Don't care states) |
| VRAM | Video RAM (Dual Ported) |
| ZBT: | Zero Bus Turnaround [no bus latency, NoBL memory is a synchronous-burst SRAM. ZBT SRAM devices use the full bandwidth because they do not require turnaround cycles (idle cycles between read and write operations)] |
This is a list of Electronic Engineering Abbreviations used with Memory ICs. The list only concerns integrated circuit memory. A separate list handles Memory Module Acronyms, with of course some of the abbreviations being the same. In most cases the links provides an in depth definition of the term.
