Latest Patents

One of her latest patents is titled "Memory device and operation method thereof." This invention includes a memory cell array with multiple memory cells that store data. It features a first transmitter that transmits data to an external device through a first data line. Additionally, a ZQ controller performs a ZQ calibration operation to generate a first ZQ code for impedance matching of the first data line. The first transmitter encodes the first ZQ code and the first data based on a first clock and drives the first data line based on the encoded result using a second clock.

Another notable patent is for a "Semiconductor memory device that includes a refresh control circuit that maintains a refresh cycle when an MRS code signal is changed due to temperature." This invention comprises a memory circuit with several memory cells and a refresh control circuit. The refresh control circuit determines the number of times to perform a target row refresh (TRR) in response to a mode register set (MRS) code signal, which is generated due to temperature changes. It is designed to maintain a refresh cycle for at least two memory cells when the refresh cycle is altered because of temperature fluctuations.
