Abstract: A memory controller that includes, in one implementation, a memory interface and a controller circuit. The memory interface is configured to interface with a non-volatile memory. The controller circuit is configured to receive a skewed codeword read from the non-volatile memory. The controller circuit is also configured to scan the skewed codeword by inserting or removing a quantity of bits at different locations in the skewed codeword and determining resulting syndrome weights of the skewed codeword. The controller circuit is further configured to determine an adjusted codeword by inserting or removing the quantity of bits at one of the different locations in the skewed codeword which results in a smallest syndrome weight. The controller circuit is also configured to decode the adjusted codeword.

Abstract: A data storage device including, in one implementation, a non-volatile memory device and a controller coupled to the non-volatile memory device. The non-volatile memory device includes a memory block. The controller is configured to receive a cycle operation request and perform a wear-level mitigation operation in response to receiving the cycle operation request. To perform the wear-level mitigation operation, the controller is configured to determine a read state condition of the memory block, perform the requested cycle operation, and increment a cycle count of the memory block by a value based on the determined read state condition of the memory block. The first read state of the memory block and the second read state of the memory block are based on a wordline voltage that is associated with the memory block.

Abstract: A data storage device is configured to mark data for refresh in response to determining that a first measured temperature associated with writing the data to the memory exceeds a first threshold. The data storage device is further configured to refresh the marked data in response to determining that a second measured temperature associated with the memory is below a second threshold.

Abstract: Time division peak power management in non-volatile memory systems is disclosed. The memory system has a memory controller and a number of semiconductor dies. Each die is assigned a time slot in which to perform high current portions of memory operations. The memory controller provides an external clock to each die. Each die tracks repeating time slots based on the external clock. The memory controller may synchronize this tracking. If a die is about to perform a high current portion of a memory operation, the die checks to determine if its allocated slot has been reached. If not, the die halts the memory operation until its allocated time slot is reached. When the allocated time slot is reached, the halted memory operation is resumed at the high current portion. Therefore, the high current portion of the memory operation occurs during the allocated time slot.

Here, the memory module is configured to program a page of non-volatile memory with a first number of program cycles and indicate (e.g., to a host) that the page is partially programmed. The memory module is also configured to program the page with a second number of program cycles after a predetermined time, wherein the memory module performs one or more other storage operations during the predetermined time, and indicate (e.g., to the host) that the page is fully programmed.

A plurality of sets of data latches of a non-volatile memory die are configured to facilitate transmission of data to and from a non-volatile memory medium, and each of the sets of data latches are associated with a different identifier. An on-die controller is in communication with a sets of data latches. An on-die controller is configured to receive a first command for a first memory operation comprising a selected identifier. An on-die controller is configured to execute a first memory operation on a non-volatile memory medium using a set of data latches of a plurality of sets of data latches, and the set of data latches is associated with a selected identifier.

Abstract: A device or apparatus may be configured to perform memory operations on a memory die while a current multi-level cell programming operation is being performed. In the event that a controller identifies pending memory operations to be performed in the memory die, the controller may communicate with the memory die to determine a status of auxiliary latches of the memory die. Depending on the status, the controller may determine if the memory die is in a suspend/resume period and/or which pending memory operations to have performed.
