Macronix patents a technique, extending flash memory life span.

Since flash memory chips don't usually last long, Macronix industries try to patent a technique capable of spanning flash memory's life.






Most flash modules fail after being written to and erased about 10,000 times, but Macronix found that the tired memory could be restored by baking it for extended periods of time.

(Sounds like re-balling technique to me. Like the GPU reballing tech. The concept is bake memory transistor and processor  chips but this will tend to happen automatically in components with materials that can stand the process.)

According to Macronix, they discovered that heated chips could tolerate more than 100 million write/erase cycles and erased faster at higher temperatures.

So the idea is a redesigned memory chip that packs on-board heaters for the "baking" process. 

The new modules are designed to heat focused groups of memory cells periodically to 800 °C or 1,472 °F, for a few milliseconds so that any damaged cells will be healed effectively.

 Here is a diagram showing the new chip designs:


However, there could be an issue with power usage since such a technique could possibly require adequate amounts of energy.The company though says that chips don't have to be heated often, and when they do, it can be done while prospective devices are recharging.

 That could bring new perspective in flash memory build up since there will be better long lasting memory chips with enhanced performance.

 The new patent is set to pass IEEE certification in the next days .
