Efficient training method for unmatched data output path in non-volatile memory

To reduce power consumption and circuitry requirements, the following presents an “unmatched” data output architecture, in which the clock path does not mimic the data path. To provide proper data transfers in the data output path, the clock signal is tuned at points of the clock path, such as for data transfers from internal data buses to FIFOs and from the FIFO though the multiplexers to the input / output pads. An amount of timing offset is introduced in the generation of internal transfer clocks, which can be determined as part of a valid data window training process that can be performed by the controller, such as part of the power up process. To more quickly train the memory dies and determine the timing offset for an unmatched data output architecture, replica circuits for the data path and the clock path can be introduced on to the memory dies.

Predecoders with write logic bypass path and memory structure including predecoders

Disclosed are predecoders and structures including the predecoders. Each predecoder includes, among other components, first and second latches controlled by write and read clock signals, respectively, and a multiplexer-enabled write logic bypass path. During a write, an address signal is latched by the first latch and propagated through logic downstream of the first latch (including through a write logic block) to the second latch (which is transparent). During a read, the write logic bypass path is activated so the address signal bypasses the first latch and the write logic block and is instead propagated only through logic downstream of the write logic block to the second latch (which periodically latches the received signal). In both operations, a predecoded address signal is output but, due to activation of the write logic bypass path during the read, the time between receiving the address signal and outputting the predecoded address signal is reduced.
