POWER EFFICIENT CODEWORD SCRAMBLING IN A NON-VOLATILE MEMORY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17829920 titled 'POWER EFFICIENT CODEWORD SCRAMBLING IN A NON-VOLATILE MEMORY DEVICE

Simplified Explanation

The abstract describes a patent application for a processing device in a memory sub-system that performs memory access operations using a randomized string generated from a hashed seed.

• The processing device receives a request to perform a memory access operation on a memory device.
• It determines a memory segment identifier associated with the memory access operation.
• A hash function is applied to the memory segment identifier to generate a hashed seed.
• The hashed seed is provided to a pseudo-random number generator.
• The pseudo-random number generator generates a randomized string.
• The memory access operation is performed on the memory device using the randomized string.

Potential Applications

• This technology can be applied in various memory sub-systems, such as computer systems, servers, and data centers.
• It can be used in any application that requires memory access operations, including data storage, retrieval, and processing.

Problems Solved

• This technology solves the problem of predictable memory access patterns, which can be exploited by malicious actors.
• By generating a randomized string, it adds an additional layer of security to memory access operations, making it harder for attackers to predict and exploit.

Benefits

• Improved security: The use of randomized strings makes it more difficult for attackers to predict and exploit memory access operations.
• Enhanced privacy: The randomized strings add an extra level of privacy by making it harder for unauthorized users to access and manipulate memory data.
• Increased performance: By randomizing memory access operations, this technology can potentially improve overall system performance by distributing memory requests more evenly.

Original Abstract Submitted

A processing device in a memory sub-system receives a request to perform a memory access operation on a memory device, determines a memory segment identifier associated with the memory access operation, and applies a hash function to the memory segment identifier to generate a hashed seed. The processing device further provides the hashed seed to a pseudo-random number generator to generate a randomized string, and performs the memory access operation on the memory device using the randomized string.
