Semiconductor memory apparatus

摘要

A semiconductor memory apparatus may include a write driver, a data sensing section, and a programming control section. The write driver may write an input data into a memory cell in response to a write signal. The data sensing section may generate a comparison flag signal by comparing an output data outputted from the memory cell with a reference voltage in response to a verification read signal. The programming control section may generate the write signal for an initial write operation and the verification read signal in response to a write command, and generate the write signal for a following write operation as soon as the comparison flag signal is at a predetermined level.

1. A semiconductor memory apparatus comprising:
a write driver configured to write an input data into a memory cell in response to a write signal; a data sensing section configured to generate a comparison flag signal by comparing an output data outputted from the memory cell with a reference voltage in response to a verification read signal; and a programming control section configured to generate the write signal for an initial write operation and the verification read signal in response to a write command, and generate the write signal for a following write operation as soon as the comparison flag signal is at a predetermined level.
