Abstract
A control signal generation circuit may include: a counting unit suitable for generating counting information; a first signal generation unit suitable for activating/deactivating a first signal based on the counting information, first rising information, and first falling information; a second signal generation unit suitable for activating/deactivating a second signal based on the counting information, second rising information, second falling information, and the first falling information; and a control signal driving unit suitable for driving a control signal in response to the first and second signals.
Claims11
A nonvolatile memory device comprising:
- a pipe transistor controlled in response to a pipe control signal;
- a first half string comprising a plurality of first memory cells coupled in series between a bit line and the pipe transistor;
- a second half string comprising a plurality of second memory cells coupled in series between a source line and the pipe transistor;
- and
- a pipe control signal generation unit suitable for activating the pipe control signal through two steps at time points set by first and second rising information and deactivating the pipe control signal through two steps at time points set by first and second falling information during a read or verify operation, when a first mode is set.
