There are several types of 1T DRAM memories: the commercialized Z-RAM from Innovative Silicon, the TTRAM from Renesas and the A-RAM from the UGR/CNRS consortium.

An abstraction layer managing the timer and space partitioning constraints of the platform (memory, CPU, Input/output).
Intel's Ted Hoff was assigned to studying Busicom's design, and came up with a much more elegant, 4 ICs architecture centered on what was to become the 4004 microprocessor surrounded by a mixture of 3 different ICs containing ROM, shift registers, input/output ports and RAM—Intel's first product (1969) was the 3101 Schottky TTL bipolar 64-bit SRAM.
The original System/360 models of IBM mainframe had read-only control store, but later System/360, System/370 and successor models loaded part or all of their microprograms from floppy disks or other DASD into a writable control store consisting of ultra-high speed random-access read-write memory.
Settings of hardware RAID or RAM clocking can also be adjusted as the management card needs no hard drives or main memory to operate.
He is responsible for relating the properties of long-term memory to mathematical properties of high-dimensional spaces and compares artificial neural-net associative memory to conventional computer random-access memory and to the neurons in the brain.
As suggested above, smaller amounts of RAM (mostly SRAM) are also integrated in the CPU and other ICs on the motherboard, as well as in hard-drives, CD-ROMs, and several other parts of the computer system.

Robert H. Dennard invented dynamic random-access memory (DRAM) in 1968; this 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.
In 2013, Crossbar introduced a prototype of RRAM as a chip about the size of a postage stamp that can store 1 TB of data.
The company sold a product called the NOVRAM (nonvolatile RAM) a Non-volatile random-access memory that combined an SRAM with an EEPROM.
With Qualcomm's latest quad-core Snapdragon S800 processor clocked at 2.2Ghz and 2GB of RAM, it also contains a 5.0 inch Sony's Triluminos and its X-Reality Engine for better image and video viewing.
The power consumption of SRAM varies widely depending on how frequently it is accessed; it can be as power-hungry as dynamic RAM, when used at high frequencies, and some ICs can consume many watts at full bandwidth.
In early June 2011, it unveiled a supercomputer on its site that has the most powerful processor in the world that runs Red Hat Linux, with six terabytes of RAM.
