1Memory bandwidth — is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of… …
2Memory address — A digital computer s memory, more specifically main memory, consists of many memory locations, each having a memory address, a number, analogous to a street address, at which computer programs store (except when the address is in mask ROM) and… …

4Bus sniffing — or Bus snooping is a technique used in distributed shared memory systems and multiprocessors to achieve cache coherence. Although there is one main memory, there are several caches (one per processor), and unless preventative steps are taken, the …
5Memory protection — is a way to control memory access rights on a computer, and is a part of most modern operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug… …
6Memory type range register — Memory type range registers (MTRRs) are a set of processor supplementary capabilities control registers that provide system software with control of how accesses to memory ranges by the CPU are cached. It uses a set of programmable model specific …
7Memory Type Range Registers — (MTRRs) are control registers that provide system software with control of how accesses to memory ranges by the CPU are cached. It uses a set of programmable model specific registers (MSRs) which are special registers provided by most modern CPUs …
8Bus encryption — is the use of encrypted program instructions on a data bus in a computer that includes a secure cryptoprocessor for executing the encrypted instructions. Bus encryption is used primarily in electronic systems that require high security, such as… …
9Memory architecture — describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific… …
10Memory coherence — is an issue that affects the design of computer systems in which two or more processors or cores share a common area of memory.[1][2][3][4] In a uniprocessor system (whereby, in today s terms, there exists only one core), there is only one… …
