SWITCHED INTERFACE STACKED-DIE MEMORY ARCHITECTURE

摘要

Systems and methods disclosed herein include those that may receive a memory request including a requested memory address and may send the memory request directly to an address decoder associated with a stacked-die memory vault without knowing whether a repair address is required. If a subsequent analysis of the memory request shows that a repair address is required, an in-process decode of the requested memory address can be halted and decoding of the repair address initiated.

主权项

1. An apparatus, comprising:
a memory vault comprising a stacked plurality of memory arrays, each memory array of the stacked plurality of memory arrays located on a memory die of a plurality of stacked memory dies; a memory vault controller (MVC) communicatively coupled to the memory vault; and a memory vault repair logic (MVRL) component of the MVC, the MVRL to receive a memory request including a requested memory address, the MVRL including at least one lookup table to translate the requested memory address into a repair address, and the MVRL and to send one or both of the memory request and the repair address to the memory vault.
