Claims21
A One-Time Programmable (OTP) memory device comprising:
- a first OTP memory cell enabled for programming responsive to protected status associated with a second OTP memory cell configured for programming prior to the first OTP memory cell.
A method of programming a One-Time Programmable (OTP) memory device comprising:
- enabling a first OTP memory cell for programming responsive to protected status associated with a second OTP memory cell configured for programming prior to the first OTP memory cell.
A One-Time Programmable (OTP) memory device comprising:
- a plurality of OTP memory cells programmable via a common memory address configured for multiple programming operations.
A One-Time Programmable (OTP) memory device comprising:
- a plurality of OTP memory cells;
- protection cells in which the states of the plurality of OTP memory cells are written;
- and
- input controllers, connected respectively to OTP memory blocks, each including one of the OTP memory cells and a protection cell corresponding to that OTP memory cell, which control the programming of the OTP memory cells so that the OTP memory cells in each OTP memory block are sequentially programmed in response to a reset signal.
