Programmable read-only memory

ROM, PROM, EPROM is Read Only Memory, Programmable Read Only Memory and Erasable Programmable Read Only Memory and are used for rapid sourees of information that seldom, or never need to be modified. 

To minimize the risk of data loss because of power failure or other reasons, the Mossbauer data are copied to a nonvolatile EEPROM (Electrically Erasable Programmable Read-Only Memory) every 9 minutes (software selectable). As the size of the EEPROM is smaller than the SRAM, the EEPROM can accumulate only up to ten Mossbauer spectra as a subset of the data from the SRAM. These spectra are obtained from the SRAM according to a pre-defined summation strategy. 

EEPROM, electrically erasable programmable read-only memory - a FLASH memory. 

The correct versions of software must be installed and appropriate backup copies made. The correct versions of firmware must also be ehecked for their presence. This may include a physical inspection of an Electronically Programmable Read Only Memory (EPROM) to read its label. The...

Most modern computers store their BIOS on an EPROM (Erasable Programmable Read Only Memory). An EPROM can be updated using flash software. In many ways, this method is more dangerous than the old-fashioned method of replacing a chip. Since the flash software overwrites the information on the chip, if you make a mistake, your computer can become unbootable. You will want to follow the instructions very carefully ... 

EEPROM Acronym for Electrically Erasable Programmable Read-Only Memory. A memory chip that maintains its contents without electrical power, and whose contents can be erased and reprogrammed either within the computer or from an external source. EEPROMs are used where the application requires stable storage without power but may have to be reprogrammed. 

The amplifier (5) boosts the signal, eliminates temperature coefficients, and adjusts the offset. The low pass filter (6) limits the bandwidth. The drive circuit is a closed loop system to achieve a stable drive oscillation. It consists of a structure (not drawn) that detects the oscillation movement of the drive of the yaw-rate sensor element, a control unit (2), and an actuator (not drawn). The start circuit (9) initiates the drive oscillation at power on. The block (8) generates all necessary adjustment signals and includes the logic circuit for the trim and an EPROM (erasable programmable read-only memory) for the storage of the trim data.

Data processing. The microprocessor functions according to the program stored in the programmable read-only memory (PROM), a solid-state data-storage device whose contents is virtually indestructible. The main tasks of the 8-bit microprocessor are (a) control of the input multiplexer (b) start and control of the calibration cycle (c) correction of measured values according to the results of the calibration cycle (d) computation of periodic averages (e) calculation of output data (f) output of data and (g) control of peripherals. 

The cost of a microprocessor with a programmable read-only memory and a random-access memory, input output devices, and a clock is about 300 Each programmable read-only memory can handle about 1,000 words. They sell for about 5 each. 

Firmware is electronically programmable read-only memory (EPROM) acting as system software. Version control must be applied. 

Because of the sheer ubiquity of the microprocessor in every aspect of daily life, it is easy to take it for granted and overlook the fact that software (in the form of code burnt onto EPROM [electronically programmable read-only memory] chips and generally known as firmware) is also involved, with all that this implies. These implications have escaped not only the layman, for whom such lack of awareness is quite forgivable, but also the enterprises that deploy these devices in their products. At present, most of these equipment suppliers continue to see themselves, quite rightly, as engineering companies but do not also regard themselves as software houses. 

Many semiconductor products are manufactured from integrated circuits (ICs). Semiconductor products using integrated circuits are shown in Table 5.1. Memory is one typical semiconductor product using IC. RAM and DRAM are applied widely to computer memory. ROM is read-only memory. EPROM is erasable programmable read-only memory, which is widely... 

Flash memory is read and write memory, and data memories do not disappear even through loss of electric power. Therefore, flash memories are widely applied to USB memory, SD memory card, smart media, and compact flash. Flash memory is also applied to hard disks for computers. NAND flash is NAND (NOT AND gate) flash memory. EEPROM is electrically erasable programmable read-only memory, which is called flashed ROM.
