What Is the Difference Between EEPROM and Flash Memory?

With the continuous advancements in the electronics realm, users are finding it difficult to distinguish between memory storage devices. Different types of memory storage devices are utilized for various applications, all which vary based on availability, ease-of-use, speed, and other factors. For example, EEPROM is preferred when data must be accessed byte-wise. Flash memory devices, on the other hand, are just one type of storage device that are used when a large amount of data is involved.

EEPROM

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile flash memory that utilizes NOR-type logic gates to store, write, and read data. While it is faster than other storage devices, it is also more expensive. EEPROM finds use in the microcontrollers of electronic devices for the means of storing small amounts of data.

Furthermore, EEPROM can access and delete byte-wise data, and it is primarily used in systems where rewriting the code is not necessary. Additionally, EEPROM chips do not need to be taken out of a computer system when there is a need to rewrite or delete data, and one of the most commonly used EEPROM chips is the 24CXX series. Lastly, EEPROM has a low voltage operation, can filter out inputs for noise suppression, achieve bidirectional data transfer protocol, and more.

Flash Memory

In contrast, flash memory takes advantage of NAND-type logic gates to store data, and it is a cost effective choice that is used in storage devices like flash drives, SD cards, digital cameras, and more. Flash memory, or flash storage as it is sometimes called, is considered a data writing and storing technology where flash memory chips are used.

Flash memory is considered superior to its counterparts with moving components since they have low latency and data is not lost even if the system is shut off. This type of storage device allows users to rewrite and delete data in a block-wise manner that slows down the process of data extraction. There are many types of flash memory, some of which include storage array, SSD flash drive, all-flash array, NVMe storage, hybrid flash storage, etc.

The applications they serve are wide-ranging as they can be used in small storage devices like flash drives and enterprise-level systems. In fact, the introduction of flash memory in the IT sector has made data storage more economical for many businesses, and when installed into computer systems, it also improves overall performance.

Conclusion

Regardless of the memory type storage device you opt for, it is important to keep such devices secure. As they hold critical data, storage devices should be tucked away for safekeeping unless they are being actively used. If you find yourself in need of storage devices, rely on Fulfillment 3Sixty.
