Abstract
A one-time programmable (OTP) memory device includes an OTP memory cell array comprising a plurality of dummy cells and a plurality of main cell groups of main cells and an access circuit configured to write data to at least two of the cells simultaneously. The arrangement of the dummy cells and the main cell groups may allow for the reliable writing of multi-bit data to the memory array. Each of the main cell groups may include a plurality of main cells which are connected to word lines, respectively, and to bit lines, respectively. Each of the main cells may be writable and each of the dummy cells may be unwritable. Each of the main cells may include a contact layer, and the dummy cells might not include the contact layer. A supply voltage may be applied to the OTP memory cell array through the contact layer.
