Flash memory looking at an early retirement

Phase change memory. What is that you say: this is a term you’ve never heard of? That’s what I thought when I heard it. It sounds like something out of a Star Trek movie. However, phase change memory is the storage technology that just may replace the ever popular flash memory, which is also non-volatile, in as little a span of time as one year. The technology is based on research and development that was done as far back as the 1960’s, which is probably why it is near ready for mass commercial use so soon.

How could it replace flash memory so entirely you ask? Well, the facts are that the science behind the phase change chip makes it capable of writing information up to 100 000 times faster than flash. It lasts up to 1000 times longer, and may retain data for longer, so there is less chance of corruption. The only down side is that it cannot be programmed before being soldered onto a circuit board, due to the memory being susceptible to heat.

The technology is different to flash in that it uses the versatility of a specific type of glass that is a semiconductor and can be switched between two states via the application of heat. Flash on the other hand uses the more conventional silicone semiconductor transistor method to do the same.

It is being said that Intel and others might have the goods ready within the excruciatingly short space of a year. This seems like great news.
