Title: Innovations by Qiming Wu in Non-Volatile Memory Technology
Introduction
Qiming Wu is a notable inventor based in Singapore, SG, recognized for his contributions to non-volatile memory technology. He holds two patents that showcase his innovative approach to enhancing secure boot processes and fault injection detection in electronic systems.
Latest Patents
One of Qiming Wu's latest patents is focused on Non-volatile-memory (NVM) contents read return validation. This invention involves a boot read-only memory (ROM) chip unit that can perform a secure boot routine based on various operations. The processor device comprises a boot ROM chip with processing circuitry on a system board configured to perform a system board power-up according to a read operation in a one-time-programmable (OTP) memory or non-volatile memory (NVM). The OTP memory/NVM includes a spare area that can receive a first sequence pattern. The processor determines whether a secure boot indication indicates a secure boot routine and differentiates one or more read return contents of the OTP memory/NVM between wrongly read return content and trusted read return content.
Another significant patent by Qiming Wu is related to hardware-assisted fault injection detection. This invention discloses anti-fault injection systems and methods. The anti-fault injection system includes a processor, a boot ROM configured to store a series of boot instructions executable by the processor, and anti-fault injection controller circuitry. The controller circuitry is accessible to the processor while executing the boot instructions and includes interrupt/reset circuitry configured to interrupt the processor in response to a trigger, along with secure boot circuitry.
