Internal storage areas in the computer. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk.
Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information.
Listed here are some of the terminology used in conjunction to memory, and it's properties.
DDR Double data rate is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst It is usually referred to as DDR as opposed to DDR SDRAM
Die An individual rectangular pattern on a wafer that contains circuitry to perform a specific function Die are encapsulated to form the black chips that are then placed on a module
DIMM Dual inline memory module A module with signal and power pins on both sides of the board (front and back)
DRAM Dynamic random access memory A type of memory component used to store information in a computer system Dynamic means the DRAMs need a constant refresh (pulse of current through all of the memory cells) to keep the stored information (See also RAM and SRAM)
Dual Banked A memory module with two banks or rows See Bank
Dynamic Type of RAM (random access memory) To keep data in the DRAM, this data needs to be refreshed (recharged) The electric charge fades out of a DRAM like air seeps out of a balloon Because of this change, it is called dynamic
