Random access memory. A data storage device for which the order of access to different locations does not affect the speed of access, except for bursts. Data is typically stored in RAM temporarily for use by the process or while the computer is operating. FPM, EDO, SDRAM, DDR, etc. are all types of RAM.
A group of DRAMs that are tied to a single, unique chip select. Note that there is a distinction between rank (for a memory module) and bank (for a DRAM). The number of chip selects on the memory controller will determine the number of memory ranks it can support. DIMMs that have a single chip select are called 1-rank (one rank or single rank). DIMMs can have multiple chip selects, DIMMs that have two chip selects are called 2-rank (two rank or dual rank) and DIMMs that have 4 chip selects are called 4-rank (four rank or quad rank).
The amount of time required for the output data to become valid once the read and address inputs have been enabled. Generally called access time
The process used to restore the charge in DRAM cells at specific intervals.
Registers delay memory information for one clock cycle to ensure all communication from the chipset is collected by the clock edge, providing a controlled delay on heavily loaded memories.
Storage media which are designed to be removed from the computer without powering the computer off.
Rambus inline memory modules used for Rambus DRAM.
