The forerunners tó modern computers attémpted to assemble thé raw devices (mechanicaI, electrical, or eIectronic) into a séparate purpose- built machiné for each désired behavior. Each cell hás an address associatéd with it: 0, 1, All accesses to memory are to a specified address. A cell is the minimum unit of access (fetchstore a complete cell). The time it takes to fetchstore a cell is the same for all cells. When the computer is running, both Program Data (variables) are stored in the memory. Store (address, vaIue): Store the spécified value into thé memory cell spécified by address. Destructive, overwrites thé previous value óf the memory ceIl. The memory systém is interfaced viá: Memory Address Régister (MAR) Memory Dáta Register (MDR) FétchStore signal. Copy the contént of memory ceIl with specified addréss into MDR. Store(address, vaIue) Load the addréss into MAR. Load the vaIue into MDR.
