It ensures a 100,000 write cycles, and is also the fastest of the three types – single cell erase time ranges from 1 to 2.5 milliseconds. Flash memory. Memory Architecture. The next in reliability are MLC-chips. NAND is much more widely deployed than NOR. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Flash memory comes in two basic types: NOR and NAND. An erase operation on a flash chip clears the data from all pages in the block, so if some of the other pages contain active data (stuff you want to keep) you either have to copy it elsewhere first or hold off from doing the erase. Flash memory is different to most other types of electronic memory in that while reading data can be performed on individual addresses on certain types of flash memory, erase and write activities may only be performed on a block of a Flash memory. 2. Flash memory has become an integral part of our day-to-day life. Flash memory is a type of non-volatile storage medium that retains all data after power has been cut off.
