    • PROBLEM TO BE SOLVED: To provide a non-volatile semiconductor memory device capable of improving an access time in a burst mode without enlarging a chip area nor increasing power consumption. SOLUTION: A block unit BU is divided into memory mats MATA, MATB, respectively, on the basis of an internal address AE2. When the internal address AE2 is "1", ascending data read from the memory mat MATB to a start address is carried out, and also an internal address AE is incremented by an address conversion circuit and 4-word block BLK# containing a word to be selected next from the memory mat MATA. Consequently, the internal address is incremented on the basis of the start address, and a period for reading each word contained in the following 4-word block BLK# can be secured at least, and decoding processing or the like of the following input address in the period can be performed.

    • 要解决的问题:提供一种能够在不扩大芯片面积的情况下提高突发模式下的访问时间并且不增加功耗的非易失性半导体存储器件。 解决方案:块单元BU分别基于内部地址AE2分成存储器块MATA,MATB。 当内部地址AE2为“1”时,执行从存储器MAT MATB读入起始地址的升序数据,内部地址AE <4:3>由地址转换电路和4字块BLK #包含要从内存垫MATA中选择的单词。 因此,内部地址基于开始地址增加,并且可以至少确保用于读取包含在以下4字块BLK#中的每个字的周期,以及下面的输入地址的解码处理等 可以执行该周期。 版权所有(C)2005,JPO&NCIPI
