Circuit for generating and trimming phases for memory cell read operations
A read signal generator generates read signals to control read operations of a memory array. The read signal generator can be selectively controlled to generate an oscillating signal having a period that corresponds to a feature one of the read signals. The oscillating signal is passed to a frequency divider that divides the oscillating signal and provides the divided oscillating signal to an output pad. The frequency of the oscillating signal can be measured at the output pad. The frequency of the oscillating signal, and the duration of the read signal feature can be calculated from the frequency of the oscillating signal. The read signal feature can then be adjusted if needed.

Memory circuit configuration
A circuit includes a memory array, a control circuit configured to identify an address of a first row containing a weak cell, and store corresponding address information in a storage device, and an address decoding circuit including NAND pairs, inverter pairs, and a logic tree.
