Logic parity RAM, also known as fake parity RAM, is non-parity RAM that can be used in computers that require parity RAM. Logic parity RAM recalculates an always-valid parity bit each time a byte is read from memory, instead of storing the parity bit when the memory is written to; the calculated parity bit, which will not reveal if the data has ...
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
SiS 730S. The SiS 630 and SiS 730 are a family of highly integrated chipsets for Intel (Slot 1/Socket 370) and AMD (Slot A/Socket A) respectively.At the time of release they were unique in that they not only provided VGA, Audio, LAN, IDE and USB functionality on board, but were also in a single-chip solution.
CPU sockets (or CPU slots) in which one or more microprocessors may be installed. In the case of CPUs in ball grid array packages, such as the VIA Nano and the Goldmont Plus, the CPU is directly soldered to the motherboard. [2] Memory slots into which the system's main memory is to be installed, typically in the form of DIMM modules containing ...
30-pin SIMM, 256 KB capacity Two 30-pin SIMM slots on an IBM PS/2 Model 50 motherboard. Standard sizes: 256 KB, 1 MB, 4 MB, 16 MB. 30-pin SIMMs have 12 address lines, which can provide a total of 24 address bits. With an 8-bit data width, this leads to an absolute maximum capacity of 16 MB for both parity and non-parity modules (the additional redundancy-bit chip usually doe
Also, each module has eight RAM chips, but the lower one has an unoccupied space for the ninth chip; this space is occupied in ECC DIMMs. Three SDRAM DIMM slots on a ABIT BP6 computer motherboard. A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers.
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 ...
Microcontroller devices with integrated I/O and memory on-chip sometimes had no, or a small, address bus available for external devices. For example, a microcontroller family available with a 2 kilobyte address space might have a variant that brought out an 11 line address bus for an external ROM; this could be done by reassigning I/O pins as address bus pins.
