Reduction of fusible links and associated circuitry on memory dies
The number of fusible links and other circuit components required to provide memory cell redundancy are reduced by sharing physical memory locations among address banks that store memory addresses. Non-trial and error algorithms and techniques determine the number of addresses and the number of identical least significant bit (LSB) values that can share the same physical memory location. By sharing physical locations for identical LSB values, circuit hardware on a memory device (including fusible links and compare circuitry) is reduced.

Range gated holographic radar
Narrow virtual transmit pulses are synthesized by differencing long-duration, staggered pulse repetition interval (PRI) transmit pulses. PRI is staggered at an intermediate frequency IF. Echoes from virtual pulses form IF-modulated interference patterns with a reference wave. Samples of interference patterns are IF-filtered to produce high spatial resolution holographic data. PRI stagger can be very small, e.g., 1-ns, to produce a 1-ns virtual pulse from very long, staggered transmit pulses. Occupied Bandwidth (OBW) can be less than 10 MHz due to long RF pulses needed for holography, while spatial resolution can be very high, corresponding to ultra-wideband (UWB) operation, due to short virtual pulses.
