A burst refresh and a normal memory operation of a DRAM can be interspersed.

More Questions from Memory and Storage

• 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.
• 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.
