Abstract: Disclosed is an apparatus and method for providing memory cell bias information for use in memory operations. One or more memory die are selected from a group of memory die, and one or more memory blocks selected from the selected one or more memory die. A group of cells are programmed within the selected memory blocks, and one or more distributions of cell program levels associated with a group of wordlines are determined. A bias value for each wordline is then generated based on comparing one or more program levels in a distribution of program levels associated with the respective wordline with predetermined programming levels. The bias values are stored lookup table that is configured to be accessible at runtime by a memory controller for retrieval of the bias value during a program or read operation.

Abstract: Disclosed is an apparatus and method for adjusting operating parameters in a storage device. A controller in a solid state drive monitors current operating conditions of the drive's flash memory, and when the flash memory has been subjected to a predetermined number of program/erase cycles one or more stored bias values are retrieved from a storage location based on the wordline(s) associated with a current memory operation. Parameters of the memory operation are then adjusted based on the retrieved bias values, and the memory operation is performed using the adjusted parameters.

Abstract: A method for suspending an erase operation performed on a group of memory cells in a flash memory circuit is disclosed. One example method includes initiating an erase operation on one or more memory cells, the erase operation including a plurality of erase pulses, checking for receipt of a memory command after a predetermined number of erase pulses, suspending, after the predetermined number of erase pulses, the erase operation if the memory command was received, and performing a memory operation associated with the memory command.
