flash memory weight is more when full
« on: April 12, 2012, 10:40:28 am »
 flash memory weight is more when full because of the energy needed to hold the ions in place.

similar to how a pack of shuffled cards weighs more than a unshuffled pack of cards

Wrong... Flash memory is heaviest when empty...
Electrons do have mass. That is correct.
To erase a cell you place charge on the floating gate .... ( an empty flash reads all ones. A logic one indicates a gate charge. Gate is charged with electrons. ).

The flash cell has the same number of electrons either way.  The gate is a capacitor.  To charge it up you move electrons from one side to the other, the total number stays the same.  There may be some mass due to the modified energy density (m=E / c^2 and all that), but not due to the electron mass.

It is also well known and documented that a human soul weights 21 grams; and that gods do really exist; :P

need to put energy in to lower entropy of a system.
Ordering of bits provides ability to do useful work

i with you guys on this
