Techniques disclosed herein cope with temperature effects in non-volatile memory systems. A control circuit is configured to sense a current temperature of the memory system and read, verify, program, and erase data in non-volatile memory cells by modifying one or more read/verify/program/erase parameters based on a temperature compensation value. The control circuit is further configured to read, verify, program, and erase data by accessing a historical temperature value stored in the memory system, the historical temperature value comprising a temperature at which a previous read, verify, program or erase occurred and measuring a current temperature value. The control circuit determines the temperature compensation value by applying a smoothing function. The smoothing function determines the temperature compensation value by selecting either the historical temperature value or the current temperature value as the temperature compensation value based on a difference between the historical temperature value and the current temperature relative to a threshold, or calculating the temperature compensation value, different from the current temperature value or the historical temperature value, based a smoothing function which utilizes the current temperature value and the historical temperature value.

A system includes a memory array, a thermometer, and control logic, operatively coupled with the memory array and the thermometer, to perform operations including causing the thermometer to obtain a first temperature result, monitoring a time since obtaining the first temperature result, determining whether the time satisfies a threshold time condition, in response to determining that the time satisfies the threshold time condition, causing the thermometer to obtain a second temperature result from an automatic temperature reading, determining a difference between the second temperature result and a previously stored temperature result, and filtering the second temperature result based on the difference to obtain a new stored temperature result.

The operations performed by the processing device further include associating the block family with a threshold voltage offset. The operations performed by the processing device further include computing an adjustment value of the threshold voltage offset, wherein the adjustment value reflects a time period that has elapsed since a triggering event and a temperature of a memory component carrying one or more blocks of the plurality of blocks.

An in-memory computation circuit includes a memory array with SRAM cells connected in rows by word lines and in columns by bit lines. Body bias nodes of the transistors in each SRAM cell are biased by a modulated body bias voltage. A row controller circuit simultaneously actuates word lines in parallel for an in-memory compute operation. A column processing circuit processes analog voltages developed on the bit lines in response to the simultaneous actuation to generate a decision output for the in-memory compute operation. A voltage generator circuit switches the modulated body bias voltage from a non-negative voltage level to a negative voltage level during the simultaneous actuation. The negative voltage level is adjusted dependent on integrated circuit process and/or temperature conditions in order to optimize protection against unwanted memory cell data flip.

A method and system provides for execution of calibration cycles from time to time during normal operation of the communication channel. A calibration cycle includes de-coupling the normal data source from the transmitter and supplying a calibration pattern in its place. The calibration pattern is received from the communication link using the receiver on the second component. A calibrated value of a parameter of the communication channel is determined in response to the received calibration pattern. The steps involved in calibration cycles can be reordered to account for utilization patterns of the communication channel. For bidirectional links, calibration cycles are executed which include the step of storing received calibration patterns on the second component, and retransmitting such calibration patterns back to the first component for use in adjusting parameters of the channel at first component.

A memory device can dynamically select a voltage step size for programming (i.e., charging) memory cells. The memory device can increase the voltage step size to reduce programming time or decrease the voltage step size to reduce errors. The memory device can identify device conditions, such as temperature or amount of use (e.g., a count of program/erase cycles). The memory device can increase the voltage step size when the device conditions are less likely to cause errors (e.g., in a middle temperature range or below a threshold number of program/erase cycles) or can decrease the voltage step size when the device conditions are more likely to cause errors (e.g., in a high or low temperature range or above a threshold number of program/erase cycles).
