and rewritten by the micro processor.
Read Only Memory is a memory that cannot be lost easily, and can
only be read, but not written by the micro processor.
Static Random Access Memory is a type of random access memory. Its
contents can be saved only if the SRAM is provided with the
uninterrupted power supply. Unlike the DRAM, the SRAM does not
