    • A memory and method for operating it provide for increased data access speed. In an implementation, a synchronous memory or SDRAM includes a central memory region with memory blocks arranged in sets on respective opposite sides. A number of primary sense amplifier sets are provided, each set being associated with a respective set of the memory blocks and located adjacent. A row cache is provided in the central memory region, and row decoders decode a row address in response to a “bank activate” command and move data from a decoded row address into a primary sense amplifier set associated with a memory block containing the decoded row address and into the row cache, before application of a “read” command to the SDRAM. Column decoders decode a column address in response to a “read” command and for reading data from the cache in accordance with the decoded column address.
    • 用于操作它的存储器和方法提供了增加的数据访问速度。 在一个实现中,同步存储器或SDRAM包括具有在相应相对侧上以集合排列的存储器块的中央存储器区域。 提供了许多初级感测放大器组,每组都与相应的存储块集合相关联并且位于相邻的位置。 在中央存储器区域中提供行缓存,并且行解码器响应于“存储体激活”命令对行地址进行解码,并将数据从解码的行地址移动到与包含解码行的存储器块相关联的初级读出放大器组 地址并进入行缓存,然后将“读”命令应用于SDRAM。 列解码器响应于“读取”命令解码列地址,并根据解码的列地址从高速缓存读取数据。
