Abstract: Methods, systems, and apparatuses related to memory operation with multiple sets of latencies are disclosed. A memory device or system that includes a memory device may be operable with one or several sets of latencies (e.g., read, write, or write recovery latencies), and the memory device or system may apply a set of latencies depending on which features of the memory device are enabled. For example, control circuitry may be configured to enable one or more features during operations on a memory array, and the control circuitry may apply a set of latency values based on a number or type of features that are enabled. The sets of latency values may depend, for example, on whether various control features (e.g., dynamic voltage frequency scaling) are enabled, and a device may operate within certain frequency ranges irrespective of other characteristics (e.g., mode register values) or latencies applied.

Abstract: 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.

Abstract: There are provided a memory device for supporting a command bus training (CBT) mode and a method of operating the same. The memory device is configured to enter a CBT mode or exit from the CBT mode in response to a logic level of a first data signal, which is not included in second data signals, which are in one-to-one correspondence with command/address signals, which are used to output a CBT pattern in the CBT mode. The memory device is further configured to change a reference voltage value in accordance with a second reference voltage setting code received by terminals associated with the second data signals, to terminate the command/address signals or a pair of data clock signals to a resistance value corresponding to an on-die termination (ODT) code setting stored in a mode register, and to turn off ODT of data signals in the CBT mode.

Abstract: A determination that a first programming operation has been performed on a particular memory cell can be made. A determination can be made, based on one or more threshold criteria, whether the particular memory cell has transitioned from a state associated with a decreased error rate to another state associated with an increased error rate. In response to determining that the particular memory cell has transitioned from the state associated with the decreased error rate to the another state associated with the increased error rate, an operation can be performed on the particular memory cell to transition the particular memory cell from the another state associated with the increased error rate to the state associated with the decreased error rate.

Abstract: 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.

Abstract: Embodiments generally relate to a memory device. In one embodiment, the memory device includes a clock receiver circuit that receives an external clock signal and provides an internal clock signal. The memory device also includes a delay-locked loop circuit (DLL) having an input, and a circuit that receives the internal clock signal. The circuit selects which pulses of the internal clock signal are applied to the input of the DLL, such that no more than two clock pulses selected from at least three consecutive pulses of the external clock signal are applied to the input of the DLL during a predetermined interval. In another embodiment, a method includes receiving an external clock signal at a clock receiver circuit, receiving an internal clock signal from the clock receiver circuit, and selecting which pulses of the internal clock signal are applied to an input of a DLL, where no more than two clock pulses selected from at least three consecutive pulses of the external clock signal are applied to the input of the DLL during a predetermined interval.

Abstract: The systems and methods provided herein acquire a command over multiple clock cycles and fires it. When a chip select signal (CS) transitions, a first portion of a command address is captured in a first clock cycle after the CS transitions. Then, a second portion of the command address is captured in a second clock cycle immediately after the first clock cycle or in a third clock cycle immediately following the second clock cycle. An internal command is fired, using the first portion of the command address and the second portion of the command address.
