The invention relates to a method of storing items of data in a memory device. The memory device has an array of a storage locations, each identified by an address corresponding to a unique multi-bit index value. The data items consist of a multi-bit identifier value and an information value. The method includes generating a first index value corresponding to the address of a fist storage location as a first function of the identifier value of an item of data and a first number from a predetermined sequence of numbers. If the first storage location is unoccupied, the item of data is stored therein. Alternatively, if the first storage location is already occupied, a second index value corresponding to the address of a further storage location is generated as a function of the identifier value and a second number from the predetermined sequence of numbers. If the further storage location is unoccupied, the item of data is stored therein. The invention also relates to a memory device for storing items of data.
