High-Speed DC Coupled Digit Detector

The requirements, design, and performance of an integrable dc coupled digit detector array for high-speed memory systems such as the plated wire is described. The array consists of 12 detectors on 100-mil centers, on a tantalum film glass substrate using beam-lead monolithic chips. There are 218 resistors and 144 beam lead transistors formed or bonded with an area of 0.8 × 1.2 inch. Ninety-six of the transistors are monolithic differential pairs.
