Abstract : CIRCUIT TECHNIQUES AND MEMORY DEVICES FOR USE IN IMPLEMENTING A SUBMICROSECOND SIMULATION COMPUTER ARE EITHER CURRENTLY AVAILABLE OR ARE EXPECTED TO BECOME AVAILABLE WITHIN A SHORT TIME. SATURATED TRANSISTOR CIRCUITS ARE PREFERRED FOR GENERAL USAGE IN THE SYSTEM OVER OTHER FASTER AND MORE COMPLEX TECHNIQUES BECAUSE OF THE REDUCTION IN COMPLEXITY,LOWER POWER DISSIPATION, AND MORE LATITUDE IN PERMISSIBLE TOLERANCE VARIATION. A BASIC THREE-MEMORY SYSTEM HAS BEEN DEFINED WHICH PROVIDES UP TO 32,000 WORDS OF INSTRUCTION STORAGE, 16,000 WORDS OF DATA STORAGE AND 1,000 WORDS OF FAST 'SCRATCH PAD' STORAGE. THE BULK STORAGE DEVICES ARE EXPECTED TO BE COMPOSED OF FERRITE ELEMENTS WHICH MAY BE SENSED NONDESTRUCTIVELY AT A TWO-MEGACYCLE RATE. THE 'SCRATCH PAD' DEVICE WILL UTILIZE MAGNETIC FILMS WHICH MAY BE CYCLED AT A FOUR-MEGACYCLERATE
