Patent ID: 7944754

Claim:
A method of sensing a group of nonvolatile storage elements in parallel, comprising: providing a word line for accessing the group of storage elements positioned from an input end of the word line at positions x 1 , x 2 , . . . xi, . . . xn; providing an input scanning sense voltage V INWL (t) applied to the input end of the word line; predetermining a word line response function V WL (xi, t) having a voltage amplitude as a function of xi and time, the response function being the word line electrical response to the input scanning sense voltage V INWL (t) applied to the input end of the word line; with application of the sensing voltage V INWL (t) to the word line, determining a time marker ti at each storage element of the group indicating a time when the storage element begins to conduct current; and determining a threshold voltage VTi of each storage element by evaluating the word line response function at the position of the storage element and at a time indicated by the time marker ti associated with the storage element.
