Both its dynamic and static versions are volatile, meaning loss of power causes loss of information.
One kind of this device consists of a grid of magnetic tunnel junctions. Besides the magnetoresistive type, another kind of this device has one word-line and two bit-lines per charge storage cell. CAS latency is the time needed to access one of this device's modules. Its capacity can be increased by creating a paging file. Both its dynamic and static versions are volatile, meaning loss of power causes loss of information. For 10 points, what type of computer memory allows reading and writing in any order?
