Latest Patents

One of Yi-Ching Chang's latest patents is titled "Power ramping sequence control for a memory device." This invention discloses memory devices that support multiple power ramping sequences or modes. A level shifter device is operably connected to a memory macro in the memory device. The level shifter device receives at least one gating signal. Based on the state of the at least one gating signal, the level shifter device outputs one or more signals that control voltage signals in or received by the memory macro to ramp up, ramp down, or ramp up and ramp down according to one or more power ramping modes.

Another notable patent is "Integrated circuit having voltage mismatch reduction." This integrated circuit features a first circuit portion on a first level and a second circuit portion on a different second level. The first circuit portion includes a first cell with a first voltage value at a first node and a second voltage value at a second node. The second circuit portion includes a second cell coupled with the first cell, which is selectively controllable to supply a voltage to the first cell based on an instruction. This instruction is determined by a mismatch between the first and second voltage values exceeding a predetermined threshold value.
