To store bits of information operational dynamic memory is divided into cells. Each cell of dynamic memory consists: capacitor, a few transistors, and can store only one bit. If capacitor of dynamic memory cell is charged, the bit is turned on - in a cell is written logic one, if the capacitor is discharged - in a cell is written logic zero. To store one byte of data in the dynamic memory, need 8 cells, as 1 byte - it is 8 bits...
