    Abstract: A memory device comprises a plurality of independent memory sectors, external address signal inputs (2) for receiving external address signals (A0-A17) for addressing individual memory locations of the memory device, the external address signals (A0-A17) comprising external memory sector address signals (A12-A17) allowing for individually addressing each memory sector, and a memory sector selection means (11) for selecting one of the plurality of memory sectors according to a value of the external memory sector address signals (A12-A17). A first and a second alternative internal memory sector address signal paths (6,7) are provided for supplying the external memory sector address signals (A12-A17) to the memory sector selection means (11), the first path (6) providing no logic inversion and the second path (7) providing logic inversion. Programmable means (12) allows for activating either one or the other of the first and second internal memory sector address signal paths (6,7), so that a position of each memory sector in a space of values (00000h - 3FFFFh) of the external address signals (A0-A17) can be changed by activating either one or the other of the first and second internal memory sector address signal paths (6,7).

    Abstract translation: 存储器件包括多个独立的存储器扇区，用于接收用于寻址存储器件的各个存储器位置的外部地址信号（A0-A17）的外部地址信号输入（2），包括外部存储器的外部地址信号（A0-A17） 允许单独寻址每个存储器扇区的扇区地址信号（A12-A17）和用于根据外部存储器扇区地址信号（A12-A17）的值来选择多个存储器扇区之一的存储器扇区选择装置（11） 。 提供第一和第二替代的内部存储器扇区地址信号路径（6,7），用于将外部存储器扇区地址信号（A12-A17）提供给存储器扇区选择装置（11），第一路径（6）不提供 逻辑反演和第二路径（7）提供逻辑反演。 可编程装置（12）允许激活第一和第二内部存储器扇区地址信号路径（6,7）中的一个或另一个，使得每个存储器扇区在空间中的位置（00000h-3FFFFh） 可以通过激活第一和第二内部存储器扇区地址信号路径（6,7）中的一个或另一个来改变外部地址信号（A0-A17）。
