Apparatuses, systems, and methods for data strobe write timing. A memory device may receive a data strobe clock signal and serial write data during a write operation. A deserializer circuit of the memory may convert the serial write data into parallel write data using timing based on the data strobe clock signal. For example, one or more internal signals may be generated based on the data strobe clock signal and used to activate various operations of the deserializer circuit. The data strobe clock signal may also be used to activate bit lines of the memory device in order to write the parallel write data to memory cells along those activated bit lines. The memory may also receive a system clock, separate from the data strobe clock signal, which may be used for other operations of the memory. For example, in a read operation, the bit lines may be activated with timing based on the system clock.

A memory access command, column address and plurality of write data values are received within an integrated-circuit memory chip via external signaling links. In response to the memory access command, the integrated-circuit memory chip (i) decodes the column address to select address-specified sense amplifiers from among a plurality of sense amplifiers that constitute a sense amplifier bank, (ii) reads first data, constituted by a plurality of read data values, out of the address-specified sense amplifiers, and (iii) overwrites the first data within the address-specified sense amplifiers with second data constituted by one or more of the write data values and by one or more of the read data values.

A memory system includes a dynamic random access memory (DRAM) device, a second memory device, and a memory controller circuit. The memory controller circuit is coupled to the DRAM device by a first data channel configured to transfer first data between the memory controller circuit and the DRAM device on behalf of a host, and is also coupled to the DRAM device by a second data channel configured to transfer second data between the memory controller circuit and the DRAM device on behalf of the second memory device while the first data is being transferred across the first data bus.

Page data can be propagated sequentially from a section to the neighboring section, and from this section to subsequent section adjacent to it until a page register set is reached. In a described apparatus based on this page-data-copy scheme, access data from a page register (which is also used for storing the data accessed using the page-data-copy scheme) with a conditional read-access method in conjunction with an arithmetic unit can execute the arithmetic process of an AI system.

A memory package includes first, second, third, and fourth channels arranged consecutively in a clockwise direction on the memory package, each of the first, second, third, and fourth channels having access circuitry and memory arrays. In a first mode, the first channel controls access to the memory arrays in the second channel and the fourth channel controls access to the memory arrays in the third channel.

Methods, systems, and devices related to an improved driver for non-binary signaling are described. A driver for a signal line may include a set of drivers of a first type and a set of drivers of a second type. When the driver drives the signal line using multiple drivers of the first type, at least one additional driver of the first type may compensate for non-linearities associated with one or more other drivers of the first type, which may have been calibrated at other voltages. The at least one additional driver of the first type may be calibrated for use at a particular voltage, to compensate for non-linearities associated with the one or more other drivers of the first type as exhibited at that particular voltage.

First data is read out of a core storage array of a memory component over a first time interval constrained by data output bandwidth of the core storage array. After read out from the core storage array, the first data is output from the memory component over a second time interval that is shorter than the first time interval and that corresponds to a data transfer bandwidth greater than the data output bandwidth of the core storage array.

Embodiments provide a write operation circuit, a semiconductor memory, and a write operation method. The write operation circuit includes a serial-to-parallel conversion circuit, a data buffer, a DBI decoder, and a precharge module. The serial-to-parallel conversion circuit performs serial-to-parallel conversion on first DBI data of a DBI port to generate second DBI data for transmission via a DBI signal line and generates input data of the data buffer according to the second DBI data and input data of a DQ port. The data buffer determines, according to the input data of the data buffer, whether to invert the global bus. The DBI decoder receives the second DBI data, decodes the global bus data and writes the decoded global bus data into the memory bank, where the decoding comprises determining whether to invert the global bus data. The precharge module sets an initial state of the global bus to Low.

The present application provides a storage system including a data port. The data port includes a data output unit. The data output unit includes: a pull-up unit having a control terminal, a first terminal and a second terminal, a first input signal being inputted to the control terminal, the first terminal being electrically connected to a power supply, the second terminal being connected to an output terminal of the data output unit, and the pull-up unit being a first NMOS transistor; and a pull-down unit having a control terminal, a first terminal and a second terminal, a second input signal being inputted to the control terminal, the first terminal being electrically connected to a ground terminal, and the second terminal being connected to the output terminal of the data output unit.

An memory component includes a memory bank and a command interface to receive a read-modify-write command, having an associated read address indicating a location in the memory bank and to either access read data from the location in the memory bank indicated by the read address after an adjustable delay period transpires from a time at which the read-modify-write command was received or to overlap multiple read-modify-write commands. The memory component further includes a data interface to receive write data associated with the read-modify-write command and an error correction circuit to merge the received write data with the read data to form a merged data and write the merged data to the location in the memory bank indicated by the read address.
