Abstract
A semiconductor memory apparatus includes a write control code generation unit configured to generate a write control code which is updated at each pulsing timing of an external test pulse signal applied through a pad; and a data write unit configured to output a programming current pulse which has a magnitude corresponding to the code value of the write control code.
Claims18
A semiconductor memory apparatus comprising:
- a write control code generation unit configured to generate a write control code which is updated at each pulsing timing of an external test pulse signal applied through a pad;
- and
- a data write unit configured to output a programming current pulse which has a magnitude corresponding to the code value of the write control code.
A semiconductor memory apparatus comprising:
- a write control code generation unit configured to generate a write control code which is updated at each pulsing timing of a control pulse signal which is controlled in a pulsing cycle thereof according to a control code which is stored in the semiconductor memory apparatus;
- and
- a data write unit configured to output a programming current pulse which has a magnitude corresponding to the code value of the write control code.
A method for controlling a programming current pulse in a semiconductor memory apparatus to control a programmed state of a memory cell depending upon a magnitude of the programming current pulse, the method comprising the steps of:
- generating a control pulse signal which is controlled in a pulsing cycle thereof in conformity with a change in code values of control codes;
- generating write control code which is updated in code values thereof at each pulsing timing of the control pulse signal;
- and
- outputting a programming current pulse which has a magnitude corresponding to the code value of the write control code.
