5, RAM: random Access Memory (andom Access Memory), that is, the memory in the mobile phone, is the memory in the chip and the CPU directly exchange data. RAM is a volatile memory, that is, once the power is lost, all the stored data will be lost. RAMWhat does eprom mean? '> What does eeprom mean?
1, eeprom is live erasable programmable read-only memory. Electrically Erasable Programmable read only memory (EEPROM) refers to electrically erasable programmable read only memory. It is a memory chip that does not lose data after power failure. EEPROM can be erased and reprogrammed on a computer or dedicated device. Generally used in plug and play.
2, EEPROMIt means live erasable programmable read-only memory. EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a non-volatile memory that can maintain the storage of data even if the power supply is disconnected. The EEPROM can modify the stored data through electronic erasure and programming operations.
3, eeprom is the meaning of electrically erasable programmable read-only memory. The following documents are related to eeprom faults: Input/OutputMemory error cause: Input/output memory errors may be input/output memory chip open, short circuit or internal breakdown. According to the relevant protocols of SFF8472, most EEPROM errors occur when the value of A0 interval is rewritten due to misoperation or I2C conflict.

eprom: erasable programmable rom. Chip writing to use a special programmer, can be repeatedly erased and written. eeprom: electrically erasable programmable rom. Eeprom: electrically erasable programmable rom. Its writing and erasing do not need to rely on other devices, and its content is modified by electronic signals.
EEPROM (Electrically Erasable Programmable Read-Only Memory - a memory chip that does not lose data after a power failure. EEPROM can be erased and reprogrammed on a computer or dedicated device.
The disadvantage is that the internal software cannot be upgraded, and the inherent program bugs cannot be modified, and can only be changed by changing the integrated film. Electrically erasable rom can be erased and written multiple times, and the user usage characteristics are equivalent to eprom, but with some featuresAfter the program, the inherent data in the chip can be modified or rewritten, making it more convenient to upgrade the inherent program and change the bug of the source program.
EEPROM and EPROM Application differences For a small system that requires switching Settings parameters, such as baud rate, synchronous and asynchronous selection, data length, etc. can be stored in the EEPROM to develop a data sequence or table, so that users can easily complete the selection. Each time the CPU is powered on, the operating mode is set according to the parameters set in the EEPROM.
EPROM: can be erasedErasable Programmable Read Only Memory (EPROM) can use high voltage to program data to write, erase the line is exposed to ultraviolet light, the data can be erased, and can be reused. A quartz transparent window is usually reserved in the package housing for easy exposure. EEPROM: refers to live erasable programmable read-only memory.
can be interchangeable, the general storage content does not require frequent changes, in the computer as a monitor memory. But ROM is the information solidified by the manufacturerWhile PROMs, EPROMs and EEPROMs can be cured after input by the user, that is, they are programmable, with storage elements at each intersection of the storage matrix. EPROM and EEPROM can also erase the original information and rewrite the new information.
1, ◆ Memory chip (IC) classification: internal memory according to the function of storing information can be divided into random access memory RAM (RandomAccess Memory)And Read Only Memory (ROM). The information in ROM can only be read out, and cannot be modified or deleted by the operator, so it is generally used to store fixed programs, such as microcomputer management, monitoring programs, assembler, and storage of various forms.
