    • PURPOSE: A semiconductor integrated circuit device is provided to include a multi-bank memory having an appropriate layout suitable for a logic process circuit device. CONSTITUTION: A semiconductor integrated circuit device(1) includes a processor(CPU)(2) integrated on a semiconductor chip and a DRAM macro(3) serving as a main memory for the CPU(2). DRAM macro(3) has a rectangular shape and includes subbanks(4a,4b,4c,4d) arranged respectively in four regions. Subbanks(4a,4c) constitute a bank A and sub banks(4b,4d) constitute a bank B. These subbanks(4a-4d) have the same configuration. Specifically, subbank(4a) includes a memory array(4aa) having a plurality of dynamic memory cells arranged in rows and columns, a row decoder(4ab) for driving a row in memory array(4aa) into a selected state, a column decoder(4ac) for selecting a column in memory array(4aa), and a preamplifier.write driver block(4ad) which reads/writes data from/into a memory cell selected by row decoder(4ab) and column decoder(4ac). Similarly, subbank(4b) includes a memory array(4ba), a row decoder(4bb), a column decoder(4bc) and a preamplifier.write driver block(4bd). Subbank(4c) includes a memory array(4ca), a row decoder(4cb), a column decoder(4cc) and a preamplifier.write driver block(4cd). Subbank(4d) includes a memory array(4da, a row decoder(4db), a column decoder(4dc) and a preamplifier.write driver block(4dd).
    • 目的:提供半导体集成电路器件以包括具有适于逻辑处理电路器件的适当布局的多存储体存储器。 构成:半导体集成电路器件(1)包括集成在半导体芯片上的处理器(CPU)(2)和用作CPU(2)的主存储器的DRAM宏(3)。 DRAM宏(3)具有矩形形状并且包括分别布置在四个区域中的子库(4a,4b,4c,4d)。 子库(4a,4c)构成存储体A,子存储体(4b,4d)构成存储体B.这些子存储体(4a-4d)具有相同的结构。 具体地,子库(4a)包括具有排列成行和列的多个动态存储单元的存储器阵列(4aa),用于将存储器阵列(4aa)中的行驱动为选择状态的行解码器(4ab),列解码器 (4a),用于选择存储器阵列(4aa)中的列,以及从/从行解码器(4ab)和列解码器(4ac)选择的存储单元中读/写数据的前置放大器。写入驱动器块(4ad)。 类似地,子库(4b)包括存储器阵列(4ba),行解码器(4bb),列解码器(4bc)和前置放大器。写驱动器块(4bd)。 子库(4c)包括存储器阵列(4ca),行解码器(4cb),列解码器(4cc)和前置放大器。写入驱动器块(4cd)。 子库(4d)包括存储器阵列(4da,行解码器(4db)),列解码器(4dc)和前置放大器。写入驱动器块(4dd)。
