Abstract

We describe the first experiments to validate the concept of a high-speed, high-density random access memory. This technique is based on a hybrid of the time-domain stimulated echo and the frequency domain scheme. The basic approach we have developed is the partitioning of the absorption frequency domain into smaller bins, so that each frequency bin stores a smaller portion of information independently. The advantage of the approach is the flexibility it offers in tailoring the memory system to match the computational processor. We have demonstrated storage and retrieval of data for long time in frequency bins separated by 750 MHz. We have achieved data rates of 40 MHz.
