Static memory will maintain storage even if power is removed.
Which is not part of a hard disk drive?
The TMS44100 4M × 1 DRAM does not have a chip select (SC) input.
Which of the following best describes EPROMs?
The check sum method of testing a ROM:
Testing and troubleshooting the decoding logic will not reveal problems with the memory chips and their connections to the CPU busses.
An optical disk is an example of magnetic 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.
The most widespread application of ROMs is in the storage of data and program codes that must be available on power-down in the microprocessor-based systems. These data and program codes are called firmware because they are firmly stored in hardware.
A type of memory that is accessed serially (one location after the other) is a ________.
Static RAMs (SRAMs) use internal capacitors as basic storage elements.
A burst refresh and a normal memory operation of a DRAM can be interspersed.
ROMs retain data when the ________.
The memory operation that presents data on the memory outputs after entering a new address is called ________.
The highest-speed magnetic storage is achieved by using a floppy disk.
All rows in a 2118 dynamic RAM need to be refreshed ________.
How many storage locations are available when a memory device has 12 address lines?
Assume a ROM to be tested is compared with a known good ROM. If the checksums differ, the ROM is ________.
One of the most important specifications on magnetic media is the ________.
Once a PROM is programmed it can be changed by applying a small electrical charge.
The time from the beginning of a read cycle to the point when the data output is valid is called propagation delay.
One of the advantages of DRAMs is their ability to store data without needing periodic refreshment of the memory contents.
The basic purpose of tristate or open-collector outputs on a memory is to ________.
ROMs are used to store data that generally cannot be easily changed.
RAM stands for Readily Accessible Memory.
Dynamic memory is memory ________.
The floating-gate MOSFET is the actual storage element for EEPROMs. An electron charge will remain on the floating gate for more than 10 years unless drained off electrically.
ROM access time is defined as ________.
FIFO is formed by an arrangement of ________.
