ABSTRACT:
A method and system for protecting a memory having a plurality of blocks from modification is disclosed. The method and system include providing a plurality of one time programmable (OTP) cells and OTP cell logic coupled with the OTP cells. An OTP cell of the plurality of OTP cells corresponds to a portion of a block of the plurality of blocks. The OTP cell allows modification of the portion of the block when the OTP cell is in a first state and permanently prevents modification of the portion of the block when the OTP cell is in a second state. The OTP cell logic uses the plurality of OTP cells to select the portion of the block as corresponding to the OTP cell. This portion of the block is write protected when the OTP cell is placed in the second state.
