Abstract:
A memory device includes a memory bank with a memory cell connected to a local bit line and a word line. A first local data latch is connected to the local bit line and has an enable terminal configured to receive a first local clock signal. A word line latch is configured to latch a word line select signal, and has an enable terminal configured to receive a second local clock signal. A first global data latch is connected to the first local data latch by a global bit line, and the first global data latch has an enable terminal configured to receive a global clock signal. A global address latch is connected to the word line latch and has an enable terminal configured to receive the global clock signal. A bank select latch is configured to latch a bank select signal, and has an enable terminal configured to receive the second local clock signal.
