Patent abstract
Devices, circuits, and methods for data mask and data bit inversion encoding and decoding for a memory circuit. According to these methods and circuits, the number of data lines/pins required to encode data mask information and data bit inversion information can be reduced. In an embodiment the data mask and data inversion functions for a portion of data, such as a data word, can be merged onto a common pin/data line. In other embodiments, a data mask instruction can be conveyed through a transmitted data word itself without using any extra pins. According to these embodiments, the pin overhead can be reduced from two pins per byte to one pin per byte.
