Apparatuses, systems, and methods for refresh address masking. A memory device may refresh word lines as part of refresh operation by cycling through the word lines in a sequence. However, it may be desirable to avoid activating certain word lines (e.g., because they are defective). Refresh masking logic for each bank may include a fuse latch which stores a selected address associated with a word line to avoid. When a refresh address is generated it may be compared to the selected address. If there is a match, a refresh stop signal may be activated, which may prevent refreshing of the word line(s).

A word-line drive circuit, a word-line driver and a storage device are provided. The word-line drive circuit includes at least two SWDs. Each SWD is connected to an MWL for providing an enable signal and a sub word line. The SWD includes a holding transistor. A first end and a second end of the holding transistor are respectively connected to different sub word lines, and a gate receives a second drive signal. The SWD is configured to provide a first drive signal to a selected sub word line in response to the first drive signal and the enable signal, the selected sub word line being a sub word line connected to the first end or second end of the holding transistor, and to conduct the first end and the second end of the holding transistor in response to the first drive signal, the enable signal and the second drive signal.

A semiconductor storage device includes a memory cell array and a control circuit. The memory cell array includes a plurality of memory strings, a plurality of word lines, each of which is connected to the memory strings, and a plurality of bit lines connected to the memory strings, respectively. The plurality of bit lines are grouped into a plurality of bit line groups. The control circuit is configured to receive a read command and first address information specifying one or more of the bit line groups. The control circuit is configured to, in response to the read command, read data selectively from each memory string connected to each bit line in the one or more bit line groups specified by the first address information, and output the read data.

Provided are a memory detection method, a computer device and a storage medium. The method includes: initializing all storage units in a storage unit array; determining a plurality of target wordlines, two adjacent target wordlines being provided with a plurality of interfering wordlines therebetween; turning on the target wordlines, and performing a write operation on storage units connected to the target wordlines; performing repeatedly turn-on and turn-off of the interfering wordlines for a plurality of times; and performing a read operation on the storage units connected to the target wordlines. A write operation is performed on the storage units connected to the interfering wordlines by means of forced current sinking.

In some examples, a main word line driver may include a transistor that is driven between an on state and a high resistance state by a signal based, at least in part, on a row address. In both states, the transistor may maintain a main word line in an inactive state. When in the high resistance state, the transistor may be overridden by a decoder that drives the main word line to an active state. In some examples, a main word line driver may include a transistor maintained in a high resistance state coupled in parallel with another transistor that may be driven between an on state and an off state by a signal based, at least in part, on a row address. When the other transistor is in the off state, the high resistance state transistor may be overridden by a decoder that drives a main word line to an active state.

A memory device includes a high density or 3D data memory and a 3D reference memory. The reference memory is used to generate a reference signal used to sense data in the data memory. Conversion circuitry converts signals from one memory cell or a group of memory cells in the reference memory into a reference signal. The reference signal is applied to a sense amplifier to sense data stored in a selected memory cell in the data memory.

An in-memory computation circuit includes a memory array with SRAM cells connected in rows by word lines and in columns by bit lines. Each row includes a word line drive circuit powered by an adaptive supply voltage. A row controller circuit simultaneously actuates word lines in parallel for an in-memory compute operation. A column processing circuit processes analog voltages developed on the bit lines in response to the simultaneous actuation to generate a decision output for the in-memory compute operation. A voltage generator circuit generates the adaptive supply voltage for powering the word line drive circuits during the simultaneous actuation. A level of the adaptive supply voltage is modulated dependent on integrated circuit process and/or temperature conditions in order to optimize word line underdrive performance and inhibit unwanted memory cell data flip.
