Depending on the type of flash memory, flash devices have a shorter lifespan, with most flash products being able to withstand approximately 10,000 to 1,000,000 erase/write cycles before wear and tear begins to compromise the integrity of the memory. EEPROMs are capable of up to 1,000,000 erase/write cycles during their lifetime. One of the advantages of using EEPROMs is their improved lifetime.

Running a series of erase and write cycles on a memory device causes it to degrade over time. However, it also loses the ability to edit specific bytes, forcing the developer to rewrite entire blocks of data when changes are made. Flash memories are capable of erasing the device in large chunks of data, which greatly improves erase speed and allows the device to store information more compactly. There are several advantages and disadvantages to using either flash memory or EEPROM devices:īecause EEPROMs perform their erase functions on a byte-by-byte basis, it increases the time required to erase and edit the device, but it allows developers to edit specific parts as needed. What are the advantages and disadvantages of using flash memory versus EEPROM? Flash memory, on the other hand, which is a type of EEPROM, is architecturally arranged in blocks where data is erased at the block level and can be read or written at the byte level. Is a type of memory in which data is read, written, and erased at the byte level. While flash memory and EEPROM devices are both capable of storing information used in embedded devices, their architecture and operations for reading, writing and erasing data differ slightly.ĮEPROM stands for Electrically Erasable Programmable Read-Only Memory, They are both electronically writable and erasable memories and are microcontroller-based applications, meaning they are used either on-chip or off-chip to store information. Non-volatile memory means that the device is able to retain data without requiring a constant power supply, allowing devices to store information even when powered off. SPI flash memory and EEPROMs are both considered non-volatile memory. In this article, we will provide a background on their relationship and a comparison between the two.ĭifferences between Flash Memory and EEPROM There are several different types of SPI memory devices used in embedded systems, including flash memory and EEPROMs.
#SPI SERIAL EEPROMS SERIAL#
Memory devices can be interconnected using several different serial protocols, including SPI or Serial Peripheral Interface. In embedded systems, a memory device is a physical device that can store data that can be used to communicate or perform a specific function.
