System including memory stacks
First Claim
Patent Images
1. A memory system comprising:
- a plurality of memory stacks, each memory stack including a plurality of memory circuits, wherein the memory circuits of the plurality of memory stacks are apportioned into one or more working memory sections and one or more corresponding mirrored memory sections; and
an interface circuit operable to;
communicate with the plurality of memory stacks and a memory controller, andreceive a triggering signal from the memory controller when the memory controller detects a data read error, wherein the interface circuit is configured to stop executing data read operations on at least one working memory section, and execute data read operations on at least one corresponding mirrored memory section, upon receiving the triggering signal.

Abstract
Large capacity memory systems are constructed using stacked memory integrated circuits or chips. The stacked memory chips are constructed in such a way that eliminates problems such as signal integrity while still meeting current and future memory standards.
