Described herein is a graphics processing unit (GPU) comprising a first processing cluster to perform parallel processing operations, the parallel processing operations including a ray tracing operation and a matrix multiply operation; and a second processing cluster coupled to the first processing cluster, wherein the first processing cluster includes a floating-point unit to perform floating point operations, the floating-point unit is configured to process an instruction using a bfloat16 (BF16) format with a multiplier to multiply second and third source operands while an accumulator adds a first source operand with output from the multiplier.

Systems and methods for processing commands at a random access memory. A series of commands are received to read data from the random access memory or to write data to the random access memory. The random access memory can process commands at a first rate when the series of commands matches a pattern, and at a second, slower, rate when the series of commands does not match the pattern. A determination is made as to whether the series of commands matches the pattern based on at least a current command and a prior command in the series of commands. A ready signal is asserted when said determining determines that the series of commands matches the pattern, where the random access memory is configured to receive and process commands faster than the second rate when the pattern is matched and the ready signal is asserted over a period of multiple commands.

A method includes transferring data out of a first buffer coupled to a first plane of a plurality of planes of a memory component, where the data was previously transferred from the first plane to the first buffer responsive to an access request to sense data stored in the plurality of planes of the memory component. The method further includes transferring, subsequent to transferring the data out of the first buffer and independently of a command from a processing device, data out of a second buffer coupled to a second plane of the plurality of planes of the memory component, where the data transferred out of the second buffer was previously transferred from the second plane to the second buffer responsive to the access request.

A memory having a delayed write-back to the array of data corresponding to a previously opened page allows delays associated with write-back operations to be avoided. After an initial activation opens a first page and the read/write operations for that page are complete, write-back of the open page to the array of memory cells is delayed until after completion of a subsequent activate operation that opens a new page. Techniques to force a write-back in the absence of another activate operation are also disclosed.

A data processing apparatus for accessing a plurality of memories is provided. The data processing apparatus includes a function control circuitry and an address generation circuitry. The function control circuitry is utilized to record a first memory address where a first function is implemented after the first function is implemented and to determine which one of the plurality of memories is a target memory according to the first memory address. The address generation circuitry is utilized to output the first memory address to the target memory. In addition, the function control circuitry is configured to determine the target memory in the same processing cycle in which the address generation circuitry is configured to output the first memory address.

A memory device can include: a memory array arranged to store data lines; an interface that receives a first read command requesting bytes of data in a consecutively addressed order from a starting byte; a cache memory having a first buffer storing a first data line including the starting byte, and a second buffer storing a second data line, from the cache memory or the memory array; output circuitry that accesses data from the first buffer, and sequentially outputs each byte from the starting byte through a highest addressed byte of the first data line; and from the second buffer and sequentially outputs each byte from a lowest addressed byte of the second data line until the requested bytes of data have been output in order to execute the first read command, the contents of the first and second buffers being maintained in the cache memory.

A memory controller schedules requests to memory devices according to scores. For this purpose, the memory controller variably adjusts weights for determining the scores with respect to the requests, calculates the scores using the weights, and determines a processing order of the requests according to the scores. The memory controller includes a request queue, a scheduler, and a weight generation circuit. The request queue stores the requests provided from an external device. The scheduler calculates a score for each request included in the request queue and determines the processing order of the requests based on the scores for the requests. The weight generation circuit generates a weight vector including the weights used to calculate the scores.

Disclosed is a method of driving a semiconductor memory device, which programs first page data and second page data in a selected page of a memory cell array, the method including: transmitting a first data buffer control signal to a data buffer so that a data buffer receives the first page data; transmitting a second data buffer control signal to the data buffer so that the data buffer receives the second page data; determining a program option of the first page data; and programming the first page data and the second page data in the selected page, in which the data buffer receives at least some elements of the second page data while the determining of the program option of the first page data is performed.

In an example, a method of operating a memory device to latch data for output from the memory device may include generating a first clock edge of a first clock signal in response to a first clock edge of a second clock signal, generating a second, opposite, clock edge of the first clock signal immediately following the first clock edge of the first clock signal in response to a second, opposite, clock edge of the second clock signal immediately following the first clock edge of the second clock signal, and latching the data in response to the second clock edge of the first clock signal for output from the memory device.

The present disclosure includes apparatuses and methods for a cache architecture. An example apparatus that includes a cache architecture according to the present disclosure can include an array of memory cells configured to store multiple cache entries per page of memory cells; and sense circuitry configured to determine whether cache data corresponding to a request from a cache controller is located at a location in the array corresponding to the request, and return a response to the cache controller indicating whether cache data is located at the location in the array corresponding to the request.
