memory effect
The property of nickel-cadmium (NiCad) batteries that causes them to lose their capacity for full recharging if they are discharged repeatedly the same amount and then recharged without overcharge before they have fully drained. The term derives from the fact that the battery appears to have a memory for the amount of charging it can sustain.
The effect was first noticed in aerospace applications and has been widely misused with regard to the batteries used in portable computer devices. The memory effect is very rare in computer NiCad batteries, especially modern ones.

On a memory module keys are physical notches on the module that prevent the memory from being incorrectly installed in a computer system. Memory keys also prevent the memory from being installed into a incompatible computer system.
- memory leak
A bug in a program that prevents it from freeing up memory that it no longer needs. As a result, the program grabs more and more memory until it finally crashes because there is no more memory left.
- memory resident
Permanently in memory. Normally, a computer does not have enough memory to hold all the programs you use. When you want to run a program, therefore, the operating system is obliged to free some memory by copying data or programs from main memory to a disk. This process is known as swapping. Certain programs, however, […]
- memory-resident virus
A virus that stays in memory after it executes and after its host program is terminated. In contrast, non-memory-resident viruses only are activated when an infected application runs.
- memristance
Short for memory resistance, memristance is a property of an electronic component that lets it remember (or recall) the last resistance it had before being shut off.
