Memory and Storage
Main computer memory is usually DRAM because of its high density and low cost; cache memory is usually SRAM because of its high speed.
Testing and troubleshooting the decoding logic will not reveal problems with the memory chips and their connections to the CPU busses.
Fusible-link PROMs are programmed by removing the desired fuse links using a microscope and tweezers.
A ROM that allows the user to program data into the chip by permanently opening fusible links is the EPROM.
A group of 6 bits is also known as 1 byte.
RAMs must have a input, in addition to data in.
RAM stands for Readily Accessible Memory.
A typical RAM will read (place stored data on its outputs) whenever the Chip Select line is active and the Write Enable line is inactive.
Address multiplexing is used to reduce the number of address lines.
ROMs are used to store data that generally cannot be easily changed.
