Abstract:
1. A configurable memory cell comprising: means for one-time-programming (OTP), wherein the means for OTP is programmable and readable partly through a first control line; means for connecting the OTP means to a control node, wherein the connecting is through a second control line; means for repeatable programming, wherein the means for repeatable programming is readable, writable, and connectable to the control node partly through a third control line; means for connecting the control node to a bit-line, wherein the means for connecting the control node to a bit-line is controlled by a forth control line, and wherein the bit-line is used for writing into the OTP and the repeatable programming means as well as for reading contents of the OTP and the repeatable programming means; and a configuration wherein by connecting predetermined voltages to the bit-line and the first, the second, the third, and the forth control lines, the control node will be connected to the OTP means, the repeatable programming means, the bit-line, or to any combination thereof for device stress management and for multiple read, write, and programming options.
