    • A dual-port programmable logic device memory array is provided. Selectable-size data words may be written to and read from the array concurrently. Data is written into the array using write column decoder and data selection logic. The size of the data words handled by the write column decoder and data selection logic is controlled by mode select signals. Data is read from the array using read column decoder and data selection logic. The size of the data words handled by the read column decoder and data selection logic is also controlled by mode select signals. The write column decoder and data selection logic may be used to write data into the memory array at one selected location at the same time that the read column decoder and data selection logic is used to read data from the array at another selected location. A write row address decoder and a read row address decoder are used to independently address individual rows of memory cells in the memory array during writing and reading, respectively.
    • 提供了双端口可编程逻辑器件存储器阵列。 可选择大小的数据字可以并行写入阵列并从阵列中读取。 使用写列解码器和数据选择逻辑将数据写入阵列。 由写列解码器和数据选择逻辑处理的数据字的大小由模式选择信号控制。 使用读列解码器和数据选择逻辑从数组中读取数据。 由读列解码器和数据选择逻辑处理的数据字的大小也由模式选择信号控制。 写列解码器和数据选择逻辑可以用于在一个选定位置将数据写入存储器阵列,同时读列解码器和数据选择逻辑用于在另一选定位置从阵列中读取数据。 写入行地址解码器和读取行地址解码器分别用于在写入和读取期间独立地对存储器阵列中的存储单元的各行进行寻址。
