The two main types of flash memory, NOR flash and NAND flash, are named after the NOR and NAND logic gates.The individual flash memory cells, consisting of floating-gate MOSFETs, exhibit internal characteristics similar to those of the corresponding gates. Each Flash memory cell consists of the basic channel with the source and drain electrodes separated by the channel about 1 µm long. Flash memory is a non-volatile form of electronic data storage and as a result it is used in many areas where short and medium term data storage is needed. However this process takes upwards of twenty minutes. When samples of flash memory chips are found to have a lower lifetime it is usually caused by the manufacturing process not being optimised for the oxide growth. It also requires the memory chip to be removed from its circuit and placed in a special eraser where the UV light can be contained. Here’s the process: 1. RF connectors     Flash memory works the same as RAM. A typical block size will be 64, 128, or 256 kB. Flash memory works much faster than traditional EEPROMs because it writes data in chunks, usually 512 bytes in size, instead of 1 byte at a time. Flash Memory Tutorial Includes: If I use super high water pressure, I can force water into the balloon. Essentially, the data is stored in the memory cells according to their state and following the usual binary code: in the ones the logical “door” is open, and in the zeros it is closed. Focus on Test from Rohde & Schwarz offers a huge number of informative PDFs, white-papers, webinars videos and general information on many test topics. Like its sibling the EEPROM, or electrically-erasable programmable read-only memory, it can be read and erased without any moving parts. ( Log Out /  This was caused by the destructive breakdown of the thin gate oxide layer. Generally the erase process is only made to last a few milliseconds. Flash memory is made of solid-state chips in which the transistors are connected, so they function similarly to the logic gate type called NAND. It uses electricity to store data rather than a head to write like a hard drive. It is also a non-volatile form of computer memory and one of the most user friendly forms as well.
