Slow down CPU speed to enhance Write Endurance to enhance life of RAM.

Upon observing the number of writes for SRAM and DRAM
The write endurance is 10 power 16.

Our CPUs are running at the speed of 1Ghz and above.

Assuming that our CPUs are running at 1Ghz,

It constantly writes in the Graphic memory.

So, the life of the DRAM chip is
10pow16 / 10pow9 which is 10pow7.
Dividing 10pow7 by 86400 (sec per day ) it is 115 days.

So the life of the SDRAM is only 115 days.

We have to somehow improve this to improve the life of a computer.

What is the required speed of the graphic memory system?

Let us assume that we have a 1600X900 monitor which is 1.4 Mega pixel.
Suppose, it has to refresh 30 times per second,
Then the display system needs 42 Mega Pixel per sec
Even if the system has to run Full HD 100 Mega pixel per second is enough.
Assuming we require 32bits per pixel 32bpp, if the system is 32bits
The system needs to run only at 100Mhz.

It is enough that the GPU runs at 100Mhz beyond which the human eyes cannot see.

Secondly, Currently most of the systems CPU is less than 1% used. So we do not need 1Gh
we only need 10Mhz to do 99% of jobs in the computer.
Even if we have 10 times the load at burst mode,
100 Mhz is more than enough for the CPU.

So integrate CPU + GPU + North Bridge etc into one CHIP APU at 100 Mhz
By doing so, The life of the RAM will increase from 115 days to 1150days.

By consiously reducing the speed further by 50% and only allowing
1600X900 displays we can bring down the speed of the APU to 50Mhz.
That would improve the life of the RAM to 2000 days.

2000 days should be the mininum life of the system.

Kindly do the needful.
