DRAM uses a cross-transistor configuration.

More Questions from Memory and Storage

• When two or more devices try to send their own digital levels to a shared data bus at the same time, bus contention will take place.
• A typical RAM will write (store data internally) whenever the Chip Select line is active and the Write Enable line is inactive.
• RAM is nonvolatile.
• Dynamic memories, such as the 2118 16K × 1 RAM, have to multiplex the address bus.
• The time from the beginning of a read cycle to the point when the data output is valid is called propagation delay.
• Most flash chips use a bulk erase operation in which all cells on the chip are erased simultaneously.
• In a register stack, data moves up but not down.
• Static memory will maintain storage even if power is removed.
• The main advantage of bipolar (TTL) memories over MOS memories is speed.
• Cache memory is used in high-speed systems.
