Abstract:
The present disclosure includes methods, devices, and systems for access line biasing. One embodiment includes selecting, using a controller external to the memory device, a particular access line dependent biasing scheme and corresponding bias conditions for use in performing an access operation on an array of memory cells of the memory device, and performing the access operation using the selected particular access line dependent biasing scheme and corresponding bias conditions. In one or more embodiments, the selected particular access line dependent biasing scheme and corresponding bias conditions is selected by the controller external to the memory device based, at least partially, on a target access line of the array.
Abstract:
An apparatus has a controller. The controller is configured to address a non-defective memory block of a sequence of memory blocks in place of a defective memory block of the sequence of memory blocks such that the non-defective memory block replaces the defective memory block. The non-defective memory block is a proximate non-defective memory block following the defective memory block in the sequence of memory blocks that is available to replace the defective memory block. The controller is configured to apply a voltage-delay correction to the non-defective memory block that replaces the defective memory block based on the actual location of the non-defective memory block.
Abstract:
Methods for sensing, method for programming, memory devices, and memory systems are disclosed. In one such method for sensing, a counting circuit generates a count output and a translated count output. The count output is converted into a time varying voltage that biases a word line coupled to memory cells being sensed. Target data for each memory cell is stored in a data cache associated with that particular memory cell. When it is detected that a memory cell has turned on, the translated count output associated with the count output that is indicative of the voltage level that turned on the memory cell is compared to the target data. The comparison determines the state of the memory cell.
