Title:
MEMORY, PROGRAMMING METHOD AND PROGRAMMING VERIFICATION METHOD FOR MEMORY, AND MEMORY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/028846
Kind Code:
A1
Abstract:
A memory, a programming method and programming verification method for a memory, and a memory system. The programming verification method comprises: obtaining an ith verification result of an ith programming verification operation, a programming state range of the ith programming verification operation being an nth state to an (n+k)th state, i and n being positive integers, k being a natural number, and the (n+k)th state being less than or equal to the highest programming state of the memory (S100); according to a verification subresult of the nth state and a verification subresult of the (n+k)th state in the ith verification result, determining a programming state range to be verified in an (i+1)th programming verification operation (S110); and according to the determined programming state range to be verified in the (i+1)th programming verification operation, performing the (i+1)th programming verification operation (S120).
