US 12,119,819 B1 · Power-up switch-interconnect configuration

Abstract

In an integrated circuit component having a switch interconnect network and a configuration memory, a constituent multiplexer of the switch interconnect network includes a plurality of pass-gates having respective outputs coupled in common to a pass-gate output node, respective inputs that constitute respective signal inputs of the multiplexer, and control inputs coupled to receive respective pass-gate control signals having logic states according to configuration data stored within the configuration memory. Power-up control circuitry within the switch interconnect network drives the pass-gate output node of the multiplexer to a predetermined voltage level following power-up of the integrated circuit component and prior to execution of a programming operation in which one or more word-lines within the configuration memory are activated to store the configuration data within the configuration memory.
