SELF-CORRECTING SOLID STATE MASS-MEMORY ORGANIZED BY WORDS FOR A STORED PROGRAM CONTROL SYSTEM

摘要

A stored program control system, more particularly for telecommunications apparatus, includes a self-correcting, solid-state mass memory, interfaced with a processing system through a controller. The mass memory is implemented using charge-coupled technology and comprises one or more memory modules connected by a biodirectional internal bus with a control module. Each memory module consists of one or more rows of memory circuits and an input/output device connecting these memory circuits with the internal bus. The control module consists of a microprogrammed time base, an adressing control circuit, and a self-correcting logic circuit, the control module being connected to the internal bus by a further input/output device for distributing data to the memory modules of the controller.
