Large capacity NDRO core memory

This paper described an NDRO rewritable high speed random access memory which is operated with a 2.5D mode at the write cycle, with a unit capacity of 4096 words of 144 bit length. This memory, with a very high speed of 250 ns read cycle, 750 ns split write cycle, was attainded by permeability sensing with novel ferrite material. This new electronically alterable NDRO core memory, having a low power consumption of 0.02 mW/bit at the read cycle and 0.2 mW/bit at the write cycle, with high data transfer rate of 5 × 10⁸bits/s, was developed.
