Abstract:
Techniques are provided for writing a high-level state to a memory cell capable of storing three or more logic states. After a sense operation performed by a first sense component and a second sense component, a digit line may be isolated from the first sense component and the second sense component. The high-level state may be stored in the memory cell, then a second state may be stored in the memory cell, in which the second state may be a mid-level state or a low-level state. The second state may be stored based on a write-back component identifying that the second state was stored in the memory cell before the write back procedure.
