Researchers in Taiwan have found a brief jolt of 800C heat can stop flash memory wearing out, Usually flash memory reliability suffers significantly after about 10,000 write and read cycles, But using this new method, the researchers have found to make them last 100 million cycles.
Using this data researchers at electronics company Macronix have found a way by re-designing chips to put a heater alongside the memory material that holds the data. They said their on-board heater applied a jolt of heat to small groups of memory cells. Briefly heating those locations to about 800C returned damaged memory locations to full working order.
I wonder if my old pen drive work if i threw it in an oven !
