How many address bits are required for a 4096-bit memory organized as a 512 × 8 memory?
A burst refresh and a normal memory operation of a DRAM can be interspersed.
The address-decoding scheme for a 16K-byte EPROM memory system requires a 1-to-8-address decoder when 4K × 8 memory is used.
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.
