INTEGRATED CIRCUIT WITH ON-DIE DISTRIBUTED PROGRAMMABLE PASSIVE VARIABLE RESISTANCE FUSE ARRAY AND METHOD OF MAKING SAME

摘要

An integrated circuit employs a plurality of functional blocks, such as but not limited to, processors (e.g., cores), and an on-die distributed programmable passive variable resistance memory array configured to provide configuration information for each of the plurality of functional blocks. A corresponding sub-portion of the on-die distributed programmable passive variable resistance memory array is fabricated in layers above each respective plurality of functional blocks. The on-die distributed programmable passive variable resistance memory array is used as either non-volatile prepackage configuration information store, or a non-volatile post-package configuration information store that may allow dynamic changing of hardware configuration of the functional blocks both during normal operation and prior to die packaging. A method for making the same is also disclosed.
