Abstract:
In an example apparatus, a command path receives read commands and provides respective control signals for each read command. The command path is configured to provide initial control signals for an initial read command responsive to a first clock edge of a clock signal of a plurality of multiphase clock signals and to further provide respective control signals for subsequent read commands responsive to receipt of the subsequent read commands. The example apparatus further includes a read data output circuit configured to receive the control signals from the command path and further receive read data in parallel. The read data output circuit is configured to provide the read data serially responsive to the control signals.

Abstract:
Apparatuses and methods for controlling timing circuit locking and/or latency during a change in clock frequency (e.g. gear down mode) are described herein. An example apparatus may include a timing circuit. The timing circuit may be configured to provide a clock signal to the forward path, adjust a rate of the clock signal responsive to receipt of a command to adjust the rate of the clock signal, select a feedback clock signal responsive to a loop delay of the timing circuit, and provide a control signal to an adjustable delay circuit of the forward path circuit. Another example apparatus may include a forward path configured to delay a signal based at least in part on a loop delay and a latency value, and a latency control circuit configured to provide an adjusted latency value as the latency value responsive to receipt of a command, wherein the forward path is configured to operate at least in part at an adjusted clock rate responsive to receipt of the command.
Abstract:
Apparatuses, sense circuits, and methods for controlling a clock signal to a clock tree is described. An example apparatus includes a consecutive write command detection circuit configured to detect whether a next write command is received within a consecutive write command period of a current write command responsive to the current write command provided at an output of the write command register. The example apparatus further includes a clock signal control circuit coupled to the consecutive write command detection circuit and configured to control a clock signal to an input/output (I/O) latch based on whether the consecutive write command detection circuit detects that the next write command is within the consecutive write command period.
Abstract:
Locked state detection circuits, devices, systems, and methods for detecting a locked or synchronized state of a clock synchronization circuit are described. Detection of a locked state includes a circuit including a phase detector configured to generate a delay adjustment signal in response to comparison of a forward path signal indicative of an external clock signal and a feedback path signal indicative of an output clock signal. The circuit further includes a trend detector operably coupled to the delay adjustment signal and configured to generate a locked signal indicative of an in-phase steady-state between the external clock signal and the output clock signal.
Abstract:
A memory, a system and a method for controlling dynamic burst length control data can generate clocks for both an upstream counter and a downstream counter by using substantially the same latency delayed received command indications. A downstream clock generation circuit generates a clock signal from a received command indication delayed by both a delay locked loop and latency delays stored in latency control circuits. An upstream clock generation circuit generates a clock signal from the received command indication delayed by the delay locked loop and capture indications from the latency control circuits.

Abstract:
Apparatuses and methods related to altering the timing of command signals for executing commands is disclosed. One such method includes calculating a forward path delay of a clock circuit in terms of a number of clock cycles of an output clock signal provided by the clock circuit and adding a number of additional clock cycles of delay to a forward path delay of a signal path. The forward path delay of the clock circuit is representative of the forward path delay of the signal path and the number of additional clock cycles is based at least in part on the number of clock cycles of forward path delay.
Abstract:
Methods, systems, and devices for extended error detection for a memory device are described. For example, during a read operation, the memory device may perform an error detection operation capable of detecting single-bit errors, double-bit errors, and errors that impact more than two bits and indicate the detected error to a host device. The memory device may use parity information to perform an error detection procedure to detect and/or correct errors within data retrieved during the read operation. In some cases, the memory device may associate each bit of the data read during the read operation with two or more bits of parity information. For example, the memory device may use two or more sets of parity bits to detect errors within a matrix of the data. Each set of parity bits may correspond to a dimension of the matrix of data.

The first column plane may include a first edge, a second edge, and a first number of digit lines arranged between the first edge and the second edge. The second column plane may include a third edge positioned adjacent to the second edge, a fourth edge, and a second number of digit lines arranged between the third edge and the fourth edge. The data-steering circuit may be configured to logically relate a first digit line of the first number of digit lines to a second digit line of the second number of digit lines, the first digit line proximate to the first edge and the second digit line proximate to the fourth edge. Associated systems and methods are also disclosed.
