Latest Patents

Rasmus Madsen's latest patents include a data storage device and a method for hiding tweak generation latency. This invention involves a decryption engine capable of decrypting encrypted data read from a physical address in a memory of a data storage device. The decryption engine utilizes a tweak value generated from a logical address associated with the physical address. To minimize latency, the tweak value is generated in parallel with the translation of the logical address to the physical address. Additionally, the tweak value is stored in a tweak buffer within the decryption engine until it is required, indexed by a tag associated with the requesting process. The tweak buffer can utilize static random-access memory (SRAM) or content-addressable memory (CAM).

Another significant patent involves memory controller support for mixed reads. This technology controls reads in a memory device that supports different types of reads with varying performance times. The memory controller can mix these different read types and tracks expected usage of the data bus to schedule read commands accordingly, thereby avoiding data collisions. A countdown timer is employed to monitor the earliest clock cycle for returning data for new read commands, ensuring efficient data management.
