The structure providing the capacitance, as well as the transistors that control access to it, is collectively referred to as a DRAM cell. They are the fundamental building block in DRAM arrays. Multiple DRAM memory cell variants exist, but the most commonly used variant in modern DRAMs is the one-transistor, one-capacitor (1T1C) cell.
Main memory usually consists of DRAM, and is distinct from caches and scratchpads. mask ROM A type of read-only memory (ROM) whose contents are programmed by the integrated circuit manufacturer. memory Devices that are used to store data or programs on a temporary or permanent basis for use in an electronic digital computer. memory access pattern
Dram (unit), a unit of mass and volume, and an informal name for a small amount of liquor, especially whisky or whiskey Dynamic random-access memory , a type of electronic semiconductor memory Dram, Welsh term for a minecart , a small railway cargo truck used in a mine railway
Dynamic random-access memory (DRAM) allowed replacement of a 4 or 6-transistor latch circuit by a single transistor for each memory bit, greatly increasing memory density at the cost of volatility. Data was stored in the tiny capacitance of each transistor and had to be periodically refreshed every few milliseconds before the charge could leak ...
While the access latency of DRAM is fundamentally limited by the DRAM array, DRAM has very high potential bandwidth because each internal read is actually a row of many thousands of bits. To make more of this bandwidth available to users, a double data rate interface was developed. This uses the same commands, accepted once per cycle, but reads ...
The dram (alternative British spelling drachm; apothecary symbol ʒ or ℨ; [a] abbreviated dr) [4] [5]: C-6–C-7 [6] is a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system. [5]
Toshiba introduced bipolar DRAM memory cells for its Toscal BC-1411 electronic calculator in 1965. [18] [19] While it offered improved performance, bipolar DRAM could not compete with the lower price of the then dominant magnetic-core memory. [20] MOS technology is the basis for modern DRAM.
Rambus DRAM was developed for high-bandwidth applications and was positioned by Rambus as replacement for various types of contemporary memories, such as SDRAM. RDRAM is a serial memory bus . DRDRAM was initially expected to become the standard in PC memory , especially after Intel agreed to license the Rambus technology for use with its future ...
