Abstract
Systems and methods of synchronous memories and synchronous memory operation are disclosed. According to one illustrative implementation, a memory device is disclosed comprising memory circuitry having a memory output, the memory circuitry including a sense amplifier having a first output and a second output, a first data path coupled to the first output of the sense amplifier, the first data path including 2 latches/registers, and a second data path coupled to the second output of the sense amplifier, the second data path including a plurality latches/registers. In further implementations, various control circuitry, connections and control signals may be utilized to operate the latches/registers in the first and second data paths according to specified configurations, control, modes, latency and/or timing domain information, to achieve, for example, pipelined output latching and/or double data rate output.
