Abstract
A read-only memory arrangement and method for programming the memory arrangement are provided. The memory arrangement includes memory cells, which each have a transistor with two contacts and a control terminal, address lines, bit lines and a potential line. A combination of one of the address lines and one of the bit lines is uniquely assigned to each memory cell. The control terminal of each transistor is connected to the address line assigned to the respective memory cell. To program a memory cell into a first memory state, one of the contacts of the transistor of the memory cell is connected to the assigned bit line and the other of the contacts is connected to the potential line. To program a memory cell into a second memory state, no connections are established between the contacts of the transistor and either the assigned bit line or the potential line.
