ABSTRACT:
A data path for coupling data between a memory cell and an input/output (IO) line sense amplifier. An IO line coupling circuit is coupled to a pair of global data lines and a pair of local data lines to couple and decouple each of the global data lines to and from a voltage supply based on the voltage levels of the local data lines for the memory read operation. For the memory write operation, the IO line coupling circuit couples and decouples each of the global data lines to and from a respective one of the local data lines. The data path also includes a first precharge circuit coupled to the global data lines to couple the global data lines to ground to precharge the signal lines prior to a memory read or write operation, and can further include a test compression circuit coupled to the global data lines.
