1. Serial Flash Memory Cross Reference

What is an EEPROM? An EEPROM, or electrically erasable programmable read only memory, like a regular ROM chip, uses a grid and electrical impulses in order to create binary data. However, the difference between ROM chips and EEPROM chips is that EEPROM chips can be reprogrammed without removing them from the computer, contrary to basic ROM chips which can only be programmed one time.

A localized charge from an electrical field is all that is needed in order to erase the EEPROM chip. Also, the entire EEPROM chip does not need to be erased at one time, which therefore allows specific changes to be made. Other erasable programmable ROM (EPROM) chips must be entirely erased if any data is to be erased. EEPROMs are constructed as arrays of floating-gate transistors.

Serial Flash Memory Cross Reference

Types of EEPROMs There are several different kinds of EEPROM chips at Future Electronics. We stock many of the most common types categorized by several parameters including memory density, memory organization, nominal supply voltage, maximum clock frequency, maximum write cycle time, maximum access time and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.
