PURPOSE: Addressing circuit, memory circuit, integrated circuit, method of data discrimination and data recording method are provided to address and sense memory elements in a cross-point diode memory array. CONSTITUTION: The memory system is incorporated into an industry standard portable interface card(e.g. PCMCIA or CF) so that it is used in existing and future products with such interfaces. The memory card(10) has an I/O interface connector(12) through which communication is made between the card(10) and a device(2) to which it is coupled. The interface connector is coupled to an interface and control circuit(14) which is connected to a removable memory module(20). The memory module(20) provides circuitry for write-once data storage, including some detection, write enabling and addressing functions. The interface and control circuit(14) comprises circuitry for control, interface, detection, error correction coding(ECC) and the like for each removable memory module(20) when it is received in the card. The memory module(20) is received in a socket or the like in the memory card, so that it is removed therefrom and replaced with another memory module(20). When received in the memory card, the memory module(20) is coupled to the interface and control circuit(14) through an internal interface(16).
