Memory bandwidth — is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of… … Wikipedia
Memory timings — (or RAM timings) refer collectively to a set of four numerical parameters called CL, tRCD, tRP, and tRAS, commonly represented as a series of four numbers separated with dashes, in that respective order (e.g. 5 5 5 15). However, it is not unusual … Wikipedia
Memory latency — In computing, memory latency is the time between initiating a request for a byte or word in memory until it is retrieved. If the data are not in the processor s cache, it takes longer to obtain them, as the processor will have to communicate with … Wikipedia
Bandwidth-delay product — In data communications, bandwidth delay product refers to the product of a data link s capacity (in bits per second) and its end to end delay (in seconds). The result, an amount of data measured in bits (or bytes), is equivalent to the amount of… … Wikipedia
Memory hierarchy — Diagram of the computer memory hierarchy See also: Computer data storage The term memory hierarchy is used in the theory of computation when discussing performance issues in computer architectural design, algorithm predictions, and the lower… … Wikipedia
Memory controller — The memory controller is a digital circuit which manages the flow of data going to and from the main memory. It can be a separate chip or integrated into another chip, such as on the die of a microprocessor. This is also called a Memory Chip… … Wikipedia
Multi-channel memory architecture — Multi channel architecture is a technology that increases the transfer speed of data between the RAM and the memory controller by adding more channels of communication between them. Theoretically this multiplies the data rate by exactly the… … Wikipedia

Dynamic random access memory — (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically … Wikipedia
