[2] [3] In simple memory subsystems, the word is transferred over the memory data bus, which typically has a width of a word or half-word. In memory subsystems that use caches, the word-sized transfer is the one between the processor and the first level of cache; at lower levels of the memory hierarchy larger transfers (which are a multiple of ...
A 64 bit memory chip die, the SP95 Phase 2 buffer memory produced at IBM mid-1960s, versus memory core iron rings 8GB DDR3 RAM stick with a white heatsink Random-access memory ( RAM ; / r æ m / ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code .
As with earlier memory generations, faster DDR3 memory became available after the release of the initial versions. DDR3-2000 memory with 9-9-9-28 latency (9 ns) was available in time to coincide with the Intel Core i7 release in late 2008, [ 19 ] while later developments made DDR3-2400 widely available (with CL 9–12 cycles = 7.5–10 ns), and ...
Because the model assumes that the word size matches the problem size, that is, for a problem of size n, , the word RAM model is a transdichotomous model. [2] The model allows both arithmetic operations and bitwise operations including logical shifts to be done in constant time (the precise instruction set assumed by an algorithm or proof ...

RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...
Logic circuits without memory cells are called combinational, meaning the output depends only on the present input. But memory is a key element of digital systems. In computers, it allows to store both programs and data and memory cells are also used for temporary storage of the output of combinational circuits to be used later by digital systems.
