SEMICONDUCTOR APPARATUS AND SEMICONDUCTOR SYSTEM HAVING RANDOM CODE GENERATION CIRCUIT AND METHOD OF PROGRAMMING DATA

摘要

PURPOSE: A semiconductor device including a random code generating circuit, and a semiconductor system, and a data programming method are provided to randomly distribute a data programming level by converting input data into conversion data through a random code and programming the conversion data. CONSTITUTION: A seed code generating unit(100) generates a plurality of seed codes with code values corresponding to an input address. A plurality of linear feedback shift registers(200,300) receives one of the plurality of seed codes as an initial value and generates the random code according to the control of a clock signal. A code combining unit(400) generates the final random code by logically combining the plurality of random codes generated in a plurality of linear feedback shift registers.
