Implementing column redundancy steering for memories with wordline repowering

摘要

A method and circuit for implementing column redundancy steering for memories with wordline repowering, and a design structure on which the subject circuit resides are provided. Each respective data column receives a precharge signal applied to an associated precharge function. An inverting multiplexer is provided in a precharge path after the wordline repowering having inputs coupled to the respective precharge functions before and after the wordline repowering. The inverting multiplexer passes the precharge signal from the precharge function before the wordline repowering or from the precharge function after the wordline repowering. The inverting multiplexer is controlled by the redundancy steering control signal that activates redundancy steering.
