Abstract:
Techniques for generating clock and control signals to achieve good performance for read and write operations in memory devices are described. In one design, a clock and control signal generator within a memory device includes first and second clock generators, first and second control signal generators, and a reset circuit. The first clock generator generates a first clock signal used for read and write operations. The second clock generator generates a second clock signal used for write operations. The reset circuit generates at least one reset signal for the first and second clock generators. The reset signal(s) may have timing determined based on loading due to dummy cells. The first control signal generator generates control signals used for read and write operations based on the first clock signal. The second control signal generator generates control signals used for write operations based on the second clock signal.
