Memory modules of SK Hynix. In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [1] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were ...

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 .
The number of levels in the memory hierarchy and the performance at each level has increased over time. The type of memory or storage components also change historically. [6] For example, the memory hierarchy of an Intel Haswell Mobile [7] processor circa 2013 is: Processor registers – the fastest possible access (usually 1 CPU cycle). A few ...
(memory density) This is the total memory capacity of the chip. Example: 128 Mib. (memory depth) × (memory width) Memory depth is the memory density divided by memory width. Example: for a memory chip with 128 Mib capacity and 8-bit wide data bus, it can be specified as: 16 Meg × 8. Sometimes the "Mi" is dropped, as in 16×8.
The zero page or base page is the block of memory at the very beginning of a computer's address space; that is, the page whose starting address is zero. The size of a page depends on the context, and the significance of zero page memory versus higher addressed memory is highly dependent on machine architecture.
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The static qualifier differentiates SRAM from dynamic random-access memory (DRAM):
