Flash memories are frequently used in place of floppy or small-capacity hard disk drives in portable computers.
EEPROM and Flash memory are electrically erasable.
The floating-gate MOSFET is the actual storage element for EEPROMs. An electron charge will remain on the floating gate for more than 10 years unless drained off electrically.
More than one bit of data can occupy each memory cell.
PROMs are basically the same as mask ROMs, once they have been programmed.
Once a PROM is programmed it can be changed by applying a small electrical charge.
DRAM chips can be combined for larger capacity and word sizes using the same methods as for other memory types.
A nibble is a group of eight bits.
When a computer is executing a program of instructions, the CPU continually fetches information from those locations in memory that contain (1) the program codes representing the operations to be performed and (2) the data to be operated upon.
DRAM uses a cross-transistor configuration.
