US Patent 7106633 Write pointer error recovery systems and methods

Write pointer error recovery systems and methods are provided. A write pointer from a write pointer circuit may cause a demultiplexer circuit to direct data from a memory cell to a desired bit location in a register. A read pointer may cause a multiplexer circuit to select data from a desired bit location in the register to provide as output data or to select one of the bits of the write pointer. The write pointer may be incremented by a data strobe signal. The state of the write pointer may be determined by reading the bits of the write pointer, and the write pointer may be synchronized via a reset line. Other embodiments are also claimed and described.
