It's been a long time

It has been a long time since I last posted here. I will try to start posting here as I had intended when I started it.

New type of memory design:
Double floating gate FET (Field Effect Transistor), so what is it. It is memory that can have two 'states' It can operate as dynamic memory(the type of memory that is used in your home computer, and it can also operate as Static memory(the type of memory used in flash memory, USB thumb drives, SD cards, Compact Flash etc.)

So what does it do?
It can operate as standard memory and when signaled it can store that information into a higher area that is the static memory. This could allow some really different choices as to how it will be used. Example; you want to have your computer run like your cell phone e.g. you push a button and the phone is ready for use. Currently if you want to do this with your computer you have to leave it on. With the double gates the system will send a signal to the memory and it will make a copy of the environment in the static portion of the memory. Then your computer will shut down. when you turn it on again it will POST (Power On Self Test) then send a signal that will return the data from the static to the dynamic state. Nearly instant on! You will not have to wait for the operating system to be written from disc back to main memory. It will take several cycles
(memory cycles) to accomplish this but not nearly as long as waiting on a disc.

Another use would be for power savings. Currently your computer powers all of its memory all of the time even when it is not really needed. The double floating gate memory could be shut down by copying any content to static then wait to be called back up for use. It can be shut down partially and leave some operating.

What will really be interesting is that it can poll each memory type seperately! so it can be used to check main memory against static for errors. This also means it could be used as long term memory. One set of memory chips that may be able to act as the main memory and the storage drive all at once. It is not being proposed as this but think of the savings that could be in cell phone memory! A 16Gb (storage) iPhone with 16Gb of main memory also, but only one set of memory chips not one set for storage and another set for dynamic memory. probably a more likely scenario would be a 16Gb of flash memory for storage and 1Gb of double gate that will store the operating system and provide 1Gb of main memory also. But for now let me dream on!
