The memory capacity is the amount of data a device can store at any given time in its memory.
An external memory interface is a bus protocol for communication from an integrated circuit, such as a microprocessor, to an external memory device located on a circuit board.
A computer system has an address bus with 8 parallel lines. This means that the address bus width is 8 bits.
A special high-voltage supply that supplies the potential and energy for altering the state of certain nonvolatile memory arrays. On some devices, the presence of VPP also acts as a program enable signal (P).
