Abstract:
Apparatuses and techniques are described for managing power consumption in a memory device. When a multi -plane read command is received, a control circuit determines whether the blocks identified by the read command are fully or partially programmed. If they are fully programmed, the read command is executed while applying a common read pass voltage to the unprogrammed word lines of the respective blocks. If the blocks are not all fully programmed, the control circuit determines a last-programmed word line. If the last-programmed word lines are not equal in each block, the read command is executed while applying a base read pass voltage to the unprogrammed word lines of one or more higher-programmed blocks and a lower read pass voltage to the unprogrammed word lines of one or more lower-programmed blocks.
