Latest Patents

One of Schimke's latest patents is the Multi-dimensional parity checker (MDPC) systems and related methods for external memories. This invention provides a mechanism to check the parity of data regions within external memories. The MDPC system includes a control register and a parity checker that generates and accumulates multi-dimensional parity bits for data segments. It compares these accumulated bits to expected multi-dimensional parity bits, generating multi-dimensional error syndrome bits that represent identified comparison errors. The parity checker can operate in various modes based on values stored in the control register, including a real-time error correction mode to address errors from random accesses within integrated circuits.

Another significant patent involves key management for on-the-fly hardware decryption within integrated circuits. This system receives encrypted information from an external memory, which includes encrypted key blobs containing secret keys for encrypted software images. A key-encryption key (KEK) code is utilized to generate key-encryption keys, allowing the decryption system to access the secret keys and subsequently decrypt the software code for further processing.
