When the scratchpad is a hidden portion of the main memory then it is sometimes referred to as bump storage. In some systems [ a ] it can be considered similar to the L1 cache in that it is the next closest memory to the ALU after the processor registers , with explicit instructions to move data to and from main memory , often using DMA -based ...
A RAM drive (also called a RAM disk) is a block of random-access memory (primary storage or volatile memory) that a computer's software is treating as if the memory were a disk drive (secondary storage). RAM drives provide high-performance temporary storage for demanding tasks and protect non-volatile storage devices from wearing down, since ...
The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes). Memory storage density The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).
Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
Magnetic core memory was the standard form of computer memory until displaced by semiconductor memory in integrated circuits (ICs) during the early 1970s. [ 10 ] Prior to the development of integrated read-only memory (ROM) circuits, permanent (or read-only ) random-access memory was often constructed using diode matrices driven by address ...
The A12X is paired with 4 GB of LPDDR4X memory in the third-generation 12.9" iPad Pro and the first-generation 11" iPad Pro, or 6 GB in the 1 TB storage configurations. [14] [2] The A12Z is paired with 6 GB of LPDDR4X RAM in the fourth-generation 12.9" iPad Pro and the second-generation 11" iPad Pro. [15]
