ABSTRACT:
The electronic read-only memory has an inner and an outer casing. The inner casing is located on a secondary circuit board, from whose edge projecting laterally from the inner casing project contact elements for producing a plug contact with the contact counterelements, which are located on a circuit board of a device, which is to be equipped with the ROM. The outer casing has lateral, outwardly open gaps, which protectively receive the contact elements. Due to the fact that the free end of the contact elements is set back with respect to the opening edge of the cap-like, outer casing, the contact elements are protected against harmful contact. This also greatly simplifies the loading of a device with the ROM, because as a result of a simple plugging movement numerous contact elements can be brought into reliable contact with the contact counterelements.
