Abstract : Phase one of the program 'Ceramic Memory for Ordnance Fuzing' encompassed theoretical and experimental tasks whose purpose was to evaluate the feasibility of using ceramic material as a memory for ordnance timers. The second phase of the program, consisted of three tasks: a continuation of ceramic memory research, and a technical and economic evaluation of two magnetic means of setting digital ordnance fuzes. Prototype ceramic memories were fabricated and packaged. The MOD V memory performed satisfactorily in a temperature environment of -55 to +75 C and after being subjected to 30 Kg's in a centrifuge, followed by a 24 Kg shock in HDL's air gun. A new class of ceramic ferroelectric memory was invented; which is solidly encapsulated. Although its read/clock voltage efficiency is lower than with the resonant ceramic memory, it offers several significant features. It is particularly applicable to counters fabricated with MOS semiconductors. Magnetic cores and bobbins were shown to be technically feasible for setting bipolar transistorized counters. The former required, however, exception to some 'ground rule' considerations while the latter could not meet economic objectives. A 'low cost magnetic wire memory' was studied. It was not adaptable to the fuze requirements, primarily because of technical limitations. (Author)
