Abstract: Techniques for burst memory write operations are disclosed. In the illustrative embodiment, a memory die is limited in how quickly it can perform memory write operations that it receives from a microcontroller due to thermal constraints. The memory die can mitigate the need for the microcontroller to perform a costly rank switch to send an operation to another die by buffering memory write operations. The microcontroller can then send several consecutive memory write operations to a first memory die before switching to a second memory die. The first memory die can then perform the memory write operations while the microcontroller has moved on to other memory operations.

Abstract: Techniques to adapt the DC bias of voltage regulators for memory devices as a function of bandwidth demand are described. In one example, a non-volatile memory device includes a plurality of voltage regulator slices, wherein outputs of the plurality of voltage regulators slices are tied together to provide a voltage to perform operations on the array. The voltage regulator slices can be enabled or disabled based on a signal from a memory controller, such as an indication of an upcoming change in bandwidth demand for a rank including the memory device.

Abstract: Techniques for proximity based on-die termination (ODT) include a memory device determining what ODT setting to apply during execution of a command by another memory device that is coupled to a same data channel as the memory device based on the memory device's proximity to the other memory device and whether the command is a read command or a write command.

Abstract: Phase compensation in an I/O (input/output) circuit includes variable, programmable slope. A phase compensation circuit can apply phase compensation of one slope and dynamically change the slope of the phase compensation to allow for better tracking of environmental conditions. The phase compensation circuit can generate a linear code to apply phase compensation to lock phase of an I/O signal to a phase of a timing signal. The circuit selectively adjusts the linear code with a variable, programmable slope, where the slope defines how much phase compensation is applied per unit change in the linear code. The circuit applies the adjusted linear code to a lock loop to lock the phase of the I/O signal to the phase of the timing signal.

Abstract: A glitch-free digitally controlled oscillator (DCO) code update may be achieved by synchronizing the transfer of the DCO code update to a logic state transition of a pulse in the DCO clock output signal such that the code update may be achieved while the DCO delay chain remains in the same logic state. A state machine may provide the DCO code update and a pulsed update signal to a timing circuit. The DCO code update may be aligned with a pulse in the pulsed update signal. The timing circuit may generate a DCO code update enabled signal upon alignment of the pulse in the pulsed update signal with a state transition of a pulse in the pulsed DCO clock output. The DCO code update enabled signal may be aligned with a state transition in the pulsed DCO clock output to permit a glitch-free DCO code update.

Abstract: Phase compensation in an I/O (input/output) circuit includes a triangular control contour with a simplified generation circuit. A linear control circuit can generate a digital N-bit linear count, and route the least significant M bits [(M?1):0] for linear control for fine delay mixing of a phase compensation loop and the most significant (N?M) bits [(N?1):M] for linear control for coarse control of a delay chain for the phase compensation loop. Prior to decoding the least significant M bits for fine delay mixing, the control circuit performs a bitwise XOR (exclusive OR) of bit M with each of bits [(M?1):0] to generate M linear control bits as the linear control for fine delay mixing. The M linear control bits generate a linear control count having a triangular contour, where the linear control count continuously, repeatedly counts from 0 to (2M?1) to 0.
