Flash memory is a non-volatile computer storage chip that can be electrically erased and reprogrammed. It was developed from EEPROM (electrically erasable programmable read-only memory) and must be erased in fairly large blocks before these can be rewritten with new data. The high density NAND type must also be programmed and read in (smaller) blocks, or pages, while the NOR type allows a single machine word (byte) to be written or read independently. The NAND type is primarily used in memory cards, USB flash drives, solid-state drives, and similar products, for general storage and transfer of data. The NOR type, which allows true random access and therefore direct code execution, is used as a replacement for the older EPROM and as an alternative to certain kinds of ROM applications. However, NOR flash memory may emulate ROM primarily at the machine code level; many digital designs need ROM (or PLA) structures for other uses, often at significantly higher speeds than (economical)...

Se trata de la forma en que se juntan los chips de memoria, del tipo que sean, para conectarse a la placa base del ordenador. Son unas plaquitas alargadas con conectores en un extremo; al conjunto se le llama módulo.

La memoria principal o RAM es donde el computador guarda los datos que está utilizando en el momento presente. El almacenamiento es considerado temporal por que los datos y programas permanecen en ella mientras que la computadora este encendida o no sea reiniciada.
