Abstract: An apparatus relates generally to a clock generator is disclosed. The clock generator is coupled to receive an input clock signal and further coupled to provide an output clock signal. An address and control register is coupled to receive an address signal and the output clock signal. An access generator is coupled to receive the output clock signal. The clock generator includes: an input node coupled to receive the input clock signal; at least one pulse generator coupled to the input node to receive the input clock signal and further coupled to provide a clock control signal; and a control gate coupled to the input node to receive the input signal and further coupled to the at least one pulse generator to receive the clock control signal. The clock control signal is provided in a non-toggling state for a high-frequency mode and in a toggling state for a low-frequency mode.

Abstract: Circuits and methods for initializing a memory. Each row of the memory includes data bits and associated parity bits. A write buffer contains bit values for initializing the memory, and a control circuit performs a first set of write operations that write values from the write buffer to the data bits of the memory without writing values to the associated parity bits. The write buffer performs a second set of write operations that write values from the write buffer to the parity bits associated with the data bits without writing data to the data bits.
