An integrated circuit includes a driving circuit and an enable control circuit. The driving circuit is configured to perform a setup operation based on a first driving current and perform a preset operation, using different driving currents, based on a first enable signal and a second enable signal. The enable control circuit is configured to generate the first and second enable signals.

A signal processing circuit includes a first signal latch circuit, a second signal latch circuit, and a decoder. The first signal latch circuit receives a command address signal and is driven by an even clock; the second signal latch circuit receives the command address signal and is driven by an odd clock; and the decoder is connected to the first signal latch circuit and the second signal latch circuit, and outputs a control signal. Both the even clock and the odd clock have a frequency equal to that of a reference clock, and both the even clock and the odd clock have a rising edge aligned with a rising edge of the reference clock.

Memory controllers, devices, modules, systems and associated methods are disclosed. In one embodiment, an integrated circuit (IC) memory controller is disclosed. The IC memory controller includes a first controller command/address (C/A) interface to transmit first and second read commands for first and second read data to a first memory C/A interface of a first bank group of memory. A second command/address (C/A) interface transmits third and fourth read commands for third and fourth read data to a second memory C/A interface of a second bank group of memory. Receiver circuitry receives the first and second read data via a first data link interface and the third and fourth read data via the second data link interface. For a first operating mode, the first and second read data are received after respective first delays following transmission of the first and second read commands and at a first serialization ratio. For a second operating mode, the first and second read data are received after respective second and third delays following transmission of the first and second read commands. The second and third delays are different from the first delays and from each other. The first and second data are received at a second serialization ratio that is different than the first serialization ratio.

An example of an apparatus may include memory organized as at least one bank that includes two or more arrays, and circuitry communicatively coupled to the memory to select respective rows of the two or more arrays of a bank for a memory access operation based on an access orientation signal. Other examples are disclosed and claimed.

A processing-in-memory (PIM) device includes a command decoder configured to repeatedly output internal multiplication and accumulation (MAC) operation control signals at a predetermined cycle in response to a MAC operation command received from outside the PIM device, a MAC unit configured to perform MAC operations in response to the internal MAC operation control signals, and an address signal generator configured to repeatedly transmit internal address signals designating storage positions of weight data and vector data that are used for the MAC operations to the MAC unit at the predetermined cycle, based on an address signal received from outside the PIM device.

A memory system includes a memory controller and a memory. The memory controller selectively operates in a first mode and a second mode. In the first mode, the memory controller transmits a first command continuously during a plurality of clock cycles. In the second mode, the memory controller to mix a second command with the first command and transmit the mixture of the first command and the second command. The memory changes command latch timing depending on the first or second mode.
