UNBUFFERED - No buffer the memory is connected directly to the chipset controller, DDR, DDR2 and DDR3 modules that are used in desktops or notebooks are mostly unbuffered. BUFFERED - A buffer is used to help the system control large amount of memory. Used to describe older technology modules such as EDO and SDRAM.
There are two key operations on memory: fetch( address ) returns value without changing the value stored at that address. store( address, value ) writes new value into the cell at the given address. This type of memory is random-access, meaning that CPU can access any value of the array at any time (vs. sequential access, like on a tape). Such memories are called RAM (random-access memory.) Some memory is non-volatile, or read-only (ROM or read-only memory.)
