Abstract
One-time programmable (OTP) Electronically Programmable Read-Only Memories (EPROMs) have been used in a number of applications for many years. One drawback with these OTP EPROMs is that these nonvolatile memories tend to be slow and/or may use a considerable amount of area. Here, however, a bit cell is provided that employs a compact dual cell, which generally includes two OTP cells. These OTP cells are generally arranged in differential configuration to increase speed and are arranged to have a small impact on area.
