So what makes PCM memory more appealing than today's flash drives? Why should one bother obtain a PCM memory device, if a flash memory device ultimately does the same job?
The best answers to these questions are found through how PCM memory device functionality. We all know, now, how PCM memory stores data (See previous post), so how does this style of storage competes with today's Flash drives.
Firstly what makes a PCM memory device distinguishable to that of flash memory, is its ability to retain binary values within each cell, when integrating new values. While in flash memory, the purging of neighboring cells must occur in order to input new values. Thereby PCM memory can transfer data at a supposed 100 times faster than Flash.
Another advantage, of PCM memory has, is its extreme durability due to lack of use of high voltage levels to shepherd electrons. Thus allowing PCM to be hypothetically rewritten over ten million times compared to the several thousands of time in a flash device.
These are just a few samples of why a PCM memory device is superior over flash.
