What is the meaning of EEPROM?
electrically erasable programmable read-only memory
EEPROM (also E2PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data by allowing individual bytes to be …
What is flash memory in simple words?
Flash memory is a long-life and non-volatile storage chip that is widely used in embedded systems. It can keep stored data and information even when the power is off. It can be electrically erased and reprogrammed. Flash memory was developed from EEPROM (electronically erasable programmable read-only memory).
What is PROM EPROM memory?
PROM stands for Programmable Read Only Memory while EPROM stands for Erasable Programmable Read Only Memory, and EEPROM stands for Electrically Erasable Programmable Read-Only Memory.
What is the difference between a EEPROM and flash?
Flash memory incorporates the use of floating-gate transistors to store data. EEPROM is a type of data memory device that uses an electronic device to erase or write digital data. Flash is block-wise erasable, while EEPROM is byte-wise erasable. Flash is constantly rewritten, while other EEPROMs are seldom rewritten.
Is PROM a volatile memory?
PROM is a programmable read-only memory. It is non-volatile memory means its data will be retained even when the power is turned off. PROMs are used in digital electronic devices to store permanent data, usually low-level programs such as firmware or microcode.
What are the two types of PROM?
PROM (programmable read-only memory). EPROM (erasable programmable read-only memory). EEPROM( electrically erasable programmable ROM).
How does a PROM differ from EPROM?
PROM stands for Programmable Read Only Memory is the type of ROM is written only. The main distinction between PROM and EPROM is that, PROM may be programmed just the once implies that it may be written only 1 time whereas EPROM is erasable; therefore it may be reprogrammed.
