Flash Destroyer – Testing an EEPROM device to Death

Designing a circuit requires reading lots of data sheets. The data sheets contain lots of parameters, for Flash memory one of those values is the number of times the device can be read and written to. In the case of a Microchip 24AA01-I/P 128byte I2C EEPROM the rated number off write cycles is 1 million.

Our friend Ian Lesnet from Dangerous Prototypes has designed a device he calls the Flash Destroyer, it will write and verify a piece of flash memory until there is an error. The live stream below shows the current number which is just over 2.4 million at the time of writing this article. When will it fail? That is hard to say since it is already more than double the manufactures rated number. Put your guesses in the comments below, I am thinking that it will be around 10 million.
