Non-volatile memory cell e.g. electrically EPROM, analog parameter controlling method for integrated circuit, involves determining value of intrinsic analog parameter of system, when magnitude of system attains threshold

摘要

The method involves positioning a multi-level system of a non-volatile memory cell in operating conditions to which the magnitude of the system follows a determined threshold value. The operating conditions of the system are evaluated in a manner to allow the magnitude to attain the threshold value. A value of an intrinsic analog parameter of the system is determined, when the magnitude attains the threshold value. Independent claims are also included for the following: (a) an integrated circuit having a programmable memory (b) a control apparatus cooperating with a device of controlling a non-volatile memory cell.
