    Abstract: Machine-readable media, methods, and apparatus that generate chip selects words are disclosed. In one embodiment, an address decoder may generate an encoded chip select word to select a memory device when in an encoded chip select mode. The address decoder may also generate an unencoded chip select word to select a memory device when in an unencoded chip select mode. In one embodiment, the address decoder, in response to an address for a boot code nub, may generate a chip select word that selects the same memory device regardless of whether the address decoder is operating in an encoded or unencoded chip select mode.

    Abstract translation: 公开了生成芯片选择字的机器可读介质，方法和装置。 在一个实施例中，当处于编码芯片选择模式时，地址解码器可以生成编码芯片选择字以选择存储器件。 当处于未编码的芯片选择模式时，地址解码器还可以生成未编码的芯片选择字以选择存储器件。 在一个实施例中，地址解码器响应于引导代码nub的地址，可以生成选择相同存储器件的芯片选择字，而不管地址译码器是以编码的还是非编码的芯片选择模式操作。
