Abstract
A memory device with one or more planes having sub-blocks is disclosed. The memory device may further include a voltage switch transistor for each of sub-blocks. Additionally, the memory device may further include a row decoder for each of sub-blocks. As a result, an operation to two sub-blocks can be performed at different times. For example, using a row decoder and voltage switch transistor, a sub-block can be initially read, followed by a subsequent read of another sub-block using a separate row decoder and voltage switch transistor. By staggering the read operations through a time delay, the peak current Icc associated with the supply voltage can be reduced.
