A SOLID STATE MEMORY SYSTEM UTILIZING IMPULSE SWITCHING OF FERRITE CORES
Abstract
A high speed core memory was completed and tested for applications to radar systems at Lincoln Laboratory. The memory uses impulse switching of ferrite cores and represents a new method of binary information storage. There are 1000 words of 30-bit length organized in a linear selection system. The address is sequential, with a minimum access time to adjacent words of 1.5 microsec. The memory is composed entirely of solid state devices, and contains approximately 2600 diodes, 2700 transistors, 2100 p-n-p-n devices and 84,000 ferrite cores. The system provides access to 20 million bits of information per second when operating at an address rate of 1.5 microsec. (Author)
