What are the Advantages and Disadvantages of Using Flash Memory vs 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 where data is read, written, and erased at the byte level. While Flash memory and EEPROM devices are both able to store information used in embedded devices, their architecture and operations for reading, writing, and erasing data slightly differ.ĮEPROM, which stands for Electrically Erasable Programmable Read-Only Memory, They are both electronically writable and erasable memory and are microcontroller-based applications, which means they are used either on or off chip to store information. Nonvolatile memory means the device is capable of retaining data without the need for constant power, allowing devices to save information even when turned off. SPI Flash memory and EEPROMs are both considered to be nonvolatile memory. Differences Between Flash Memory and EEPROM Photo by Micah Elizabeth Scott on Flickr. In this article, we’ll provide a background on their relationship and a comparison between the two.Įxample of EEPROM on Circuit Board. There are multiple different types of SPI memory devices used in embedded systems, including Flash memory and EEPROMs.

Memory devices can be interfaced through multiple different serial protocols, including SPI, or Serial Peripheral Interface.
In embedded systems, a memory device is a physical device that is able to store data that can be used to communicate or perform a certain function.
