METHOD AND APPARATUS FOR TESTING ONE TIME PROGRAMMABLE (OTP) ARRAYS

摘要

An array of one time programmable (OTP) devices includes a first set of pre-configurable memory devices appended to one or more columns of the array and a second set of pre-configurable memory devices appended to one or more rows of the array. The pre-configurable memory devices may be additional OTP devices or read only memory (ROM) devices that can be configured to store a predetermined test pattern for the array. Rows, columns and functionalities of the array can be tested based on the stored test pattern. OTP devices in the array may then be programmed after successful testing based on the test pattern stored.
