Abstract: Methods, systems, and devices for transient and stable state read operations of a memory device are described. A memory system may implement a read operation including a delay if a channel is at stable state, and may implement a read operation without a delay if the channel is in a transient state. Upon receiving a read command to a set of memory cells sharing the channel, the memory system may determine whether the channel is in a stable or transient state. If the channel is in a stable state, the memory system may perform a read operation including a delay between boosting the channel and driving respective word lines, such that the channel partially discharges prior to driving the word lines. If the channel is in a transient state, the memory system may perform a read operation without a delay between boosting the channel and driving the word lines.

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.
