A matrix store for data rate conversion

A description is given of a parallel-access ferrite-core store which forms part of a data-handling system. The storage capacity is 13750 binary digits. In any 10sec period, up to 625 words of 22 digits each can be written into the store at a random rate, and over the same period, the information in the 625 storage positions is read out sequentially and destructively at a fixed rate. Thus, conversion of a random to a regular flow of information is achieved by means of the store. Some of the circuits incorporated in the store and the construction of the core matrix are described.
