Latest Patents

One of Ki-Jun Nam's latest patents focuses on grouping power supplies for a sleep mode. This invention describes methods, systems, and devices that configure a memory device with groups of internal power supplies. The voltage levels of these supplies can be successively modified according to a group order signaled by an on-die timer. For instance, when the memory device enters a deep sleep mode, the voltage levels of the first group of internal power supplies are modified to match external power supply voltage levels at a designated time. This process continues for subsequent groups, ensuring efficient power management. Upon exiting the deep sleep mode, the voltage levels are adjusted back in the reverse order.

Another notable patent involves systems and methods for controlling the common mode level for sense amplifier circuitry. In this invention, a memory device includes a memory cell that stores data, along with a pair of digit lines that carry this data. A sense amplifier is utilized to sense and amplify the voltages received at these digit lines. Additionally, a replica sense amplifier generates a common mode voltage that corresponds to the common mode voltage of the digit lines, enhancing the performance of the memory device.
