- In a computer system memory is used to store data temporarily or permanently. The capacity of the memory is normally measured in bytes. There are a number of different types of memory:
- A 32 bit processor can address 4Gb of memory, whilst a 64 bit processor can address 8Tb.
Static random access memory containing recently used information. Used to buffer the central processing unit from any slower memory devices.
Double data rate synchronous dynamic random access memory. Usually referred to as DDR.
Dynamic random access memory.
Memory that can be sequentially accessed by more than one controller or processor but not simultaneously accessed. Also known as shared memory.
Memory that can be simultaneously accessed by more than one controller or processor.
Acronym for electrically erasable programmable read only memory.
Acronym for erasable programmable read only memory, originally UVEPROM for ultraviolet erasable PROM.
An acronym for programmable read only memory. PROM is a common name for several types of field programmable nonvolatile memory integrated circuits.
