Abstract
A method and circuit to trim the internal timing conditions for a semiconductor memory device including a memory matrix and circuit portions for allowing reading of the data stored in the memory matrix wherein such circuit portions include an ATD generator detecting each transition of a plurality of address terminals of the memory device to produce an ATD synchronization signal, a sense amplifier which receives an equalization a signal EQU from a generator activated by the ATD signal, and output buffers enabled by an OUTLATCH signal produced by a generator receiving the ATD signal and the EQU signal. The length of the signals is automatically trimmed according to a corresponding length code contained in a portion of the memory device.
