Patent ID: 7675949

Claim:
A solid state memory device, comprising: a plurality of memory arrays; a plurality of data interconnects, each data interconnect dedicated to one of the plurality of memory arrays; a plurality of read multiplexers, each including an output coupled to one of the plurality of data interconnects and a plurality of inputs configured to be selectively routed to the output responsive to a select signal, each of the plurality of inputs coupled to one of the plurality of memory arrays; a plurality of write multiplexers, each including an output coupled to one of the plurality of memory arrays and a plurality of inputs configured to be selectively routed to the output responsive to a select signal, each of the plurality of inputs coupled to one of the plurality of data interconnects; and control logic configured to apply select signals to the plurality of read and write multiplexers to configure the plurality of read and write multiplexers to operate in one of a normal mode and a safe mode, wherein in the normal mode, the control logic configures each read and write multiplexer to couple each of the plurality of data interconnects to the memory array to which such data interconnect is dedicated, and in the safe mode, the control logic configures each read and write multiplexer to time multiplex and replicate data associated with each of the plurality of memory arrays over each of at least a subset of the data interconnects.
