RAM parity
RAM parity checking is the storing of a redundant parity bit representing the parity (odd or even) of a small amount of computer data (typically one byte) stored in random access memory, and the subsequent comparison of the stored and the computed parity to detect whether a data error has occurred.
The parity bit was originally stored in additional individual memory chips; with the introduction of plug-in DIMM, SIMM, etc. modules, they became available in non-parity and parity (with an extra bit per byte, storing 9 bits for every 8 bits of actual data) versions.
History
Early computers sometimes required the use of parity RAM, and parity-checking could not be disabled. A parity error typically caused the machine to halt, with loss of unsaved data; this is usually a better option than saving corrupt data. Logic parity RAM, also known as fake parity RAM, is non-parity RAM that can be used in computers that require parity RAM. Logic parity RAM recalculates an always-valid parity bit each time a byte is read from memory, instead of storing the parity bit when the memory is written to; the calculated parity bit, which will not reveal if the data has been corrupted (hence the name "fake parity"), is presented to the parity-checking logic. It is a means of using cheaper 8-bit RAM in a system designed to use only 9-bit parity RAM.

Remembered
by: SpokenI miss the way you held me to your heart
The way you promised me forever
Always promised me forever
You're walking away from me
Can't you see what you do to me
When you walk away from me
All the things that you say to me
How you never will believe
There was a time you would speak to me
When you needed something from me
Now it's your turn
Your flesh seems stronger than your love for me
Your flesh cries out only for a moment
Can't you see what you do to me
When you walk away from me
You're walking away from me
Can't you see what you do to me
When you walk away from me
All the things that you say to me
How you never will believe
There was a time you would speak to me
When you needed something from me
Now it's your turn to crucify me
Can't you see what you do to me
When you walk away from me
I would gladly give you my heart
I would gladly give my life to you
All your secrets are left behind you
Forever lost and never remembered
Another chance is all that I long for
Another chance to live my life for you
Moving onward never looking back
I would gladly give you my heart
I would gladly give my life to you
All your secrets are left behind you
Forever lost and never remembered
Another chance is all that I long for
Another chance to live my life for you
Moving onward never looking back
Can't you see what you do to me
When you walk away from me
All the things that you say to me
How you never will believe
There was a time you would speak to me
When you needed something from me
