More Questions from Memory and Storage

• When a computer is executing a program of instructions, the CPU continually fetches information from those locations in memory that contain (1) the program codes representing the operations to be performed and (2) the data to be operated upon.
• DRAM uses a cross-transistor configuration.
• 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.
