Latest Patents

One of Tsang's latest patents focuses on power management for an integrated graphics device. In this invention, he describes a mechanism that controls power consumption of a graphics memory controller hub (GMCH) through voltage and frequency adjustments of the clock signal received from a clock generator. The GMCH includes a graphics core and a circuit designed to alter operational behavior, such as adjusting the frequency of a render clock signal supplied to the graphics core. This circuit monitors the idleness of the graphics core and reduces the frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

Another significant patent by Tsang is related to a block locking and passcode scheme for flash memory. This invention involves a flash memory device that includes a first memory array, block locking circuitry, and control circuitry. The memory array consists of multiple memory blocks, each containing a memory cell. The block locking circuitry features several block lock-bits and a master lock-bit, with each block lock-bit corresponding to a memory block and indicating whether it is locked. The control circuitry is designed to receive a passcode that allows it to override the master lock-bit or one of the block lock-bits.
