Latest Patents

One of Lim's latest patents is a "Flash memory device having secure file deletion function and method for securely deleting flash file." This invention discloses a flash memory device that incorporates a secure flash file deletion function. The method involves storing data and object headers separately in data blocks and header blocks, with the data being encrypted. A decryption key is included in the object header, which is stored in the header block. When a flash file is deleted, the object header is removed by searching the header block. This method utilizes a binary tree structure to enhance the search process, making it particularly suitable for NAND flash memory devices used in embedded systems.

Another significant patent by Lim is the "Method for reducing memory power consumption." This method aims to lower memory power consumption by splitting the time allocated to a process into time slices. A timer interrupt is generated for each time slice, allowing for checks on context switches between processes. When a context switch occurs, the memory banks allocated to the switched process are activated. Conversely, if no context switch occurs, all memory banks are converted into a low power state. This innovative approach effectively reduces power consumption through a software technique.
