Abstract: Methods and apparatus related to predictive Count Fail Byte (CFBYTE) for non-volatile memory are described. In one embodiment, logic determines a number of memory cells of the non-volatile memory that would pass or fail verification in a current program loop. The logic determines the number of the memory cells based at least in part on information from a previous program loop. The previous program loop is executed prior to the current program loop. The logic causes inhibition of one or more verification pulses to be issued in the current program loop based on comparison of the information from the previous program loop and a threshold value. Other embodiments are also disclosed and claimed.

Abstract: Apparatuses and methods for performing concurrent memory access operations for multiple memory planes are disclosed herein. An example method may include receiving first and second command and address pairs associated with first and second plane, respectively, of a memory. The method may further include, responsive to receiving the first and second command and address pairs, providing a first and second read voltages based on first and second page type determined from the first and second command and address pair. The method may further include configuring a first GAL decoder circuit to provide one of the first read voltage or a pass voltage on each GAL of a first GAL bus. The method may further include configuring a second GAL decoder circuit to provide one of the second read level voltage signal or the pass voltage signal on each GAL of a second GAL bus coupled to the second memory plane.

Abstract: Systems, apparatuses and methods may provide for identifying a target sub-block of NAND strings to be partially or wholly erased in memory and triggering a leakage current condition in one or more target select gate drain-side (SGD) devices associated with the target sub-block. Additionally, the leakage current condition may be inhibited in one or more remaining SGD devices associated with remaining sub-blocks of NAND strings in the memory. In one example, triggering the leakage current condition in the one or more target SGD devices includes setting a gate voltage of the one or more target SGD devices to a value that generates a reverse voltage that exceeds a threshold corresponding to the leakage current condition.

Abstract: The inhibit voltage is a voltage applied to wordlines adjacent to a program wordline having a memory cell to write during the program operation. The inhibit voltage for a program operation can be ramped up during the program pulse. Instead of applying a constant high inhibit voltage that results in the initial boosted channel potential reducing drastically due to leakage, a system can start the inhibit voltage lower and ramp the inhibit voltage up during the program pulse. The ramping up can be a continuous ramp or in finite discrete steps during the program pulse. Such ramping of inhibit voltage can provide better tradeoff between program disturb and inhibit disturb.
