    Abstract: A semiconductor device includes an address input circuit configured to boost a voltage level of at least one bit of a row address to generate a boosting address and to drive a signal of a first node based on other bits of the row address and the boosting address. The semiconductor device also includes a word line selection signal generation circuit configured to drive a signal of a second node based on the signal of the first node and to generate a word line selection signal for selecting a word line based on the signal of the second node.

    Abstract: A request to perform a write operation at a memory device is received. Current wordline start voltage (WLSV) information associated with a particular memory segment of the plurality of memory segments is retrieved. In a firmware record in a memory sub-system controller, information is stored indicative of a last written memory page associated with the particular memory segment on which the write operation is performed. The firmware record is managed in view of the information indicative of the last written memory page associated with the performed write operation. Each entry of the firmware record comprises one or more identifying indicia associated with a respective memory segment, at least one of the identifying indicia being a wordline start voltage (WLSV) associated with the respective memory segment, and the other indicia is a plane mask. Plane mask compatibility helps identify which pages can be programmed together in a multi-plane write operation.

    Abstract: A method for multi-state programming of a non-volatile memory structure, comprising: (1) initiating a programming operation with respect to multiple program states, (2) applying, to all selected word lines of the memory structure, a programming voltage bias (VPGM) level pre-determined to be suitable for programming a highest program state of the multiple program states, wherein the programming voltage bias level is applied according to a given program pulse width, and (3) with respect to each program state other than the highest program state of the multiple program states, applying a zero-volt bitline voltage bias (VBL) to one or more bitlines that are associated with one or more memory elements to be programmed to the program state, wherein the zero-volt bitline voltage bias is applied according to a respective program sub-pulse width that is less than the given program pulse width.

    Abstract: Systems and methods are provided for controlling a sleep operation for a memory array. A memory system may include a memory array with a memory cell and a word line driver, the memory array receiving a word line clock signal that enables and disables memory read and write operations of the memory cell. The memory array may further including a switching circuit coupled between the word line driver and a power source, the switching circuit being controlled by a local word line sleep signal to turn power to the word line driver on and off. A latch circuit may generate the local word line sleep signal in response to a delayed clock signal and one or more power management control signals. The word line clock signal and the delayed clock signal may both being generated as a function of a memory clock signal. The latch circuit may synchronize the local word line sleep signal with the delayed clock signal such that the local word line sleep signal is prevented from turning off power to the word line driver until memory read and write operations of the memory cell are disabled by the word line clock signal.
