    • A memory reconfiguration system dynamically configures spare chips into memory during system operation by shifting data around defective chips. The shifting of data around an entire memory chip allows the system to correct bit, addressing, and control errors or faults within the chip. When the system detects an error, or otherwise initiates a memory reconfiguration, it transmits a configuration code to shift registers for a memory write driver. The shift registers, in response to the configuration code, shift write data so that the data is effectively shifted around a particular memory chip and into a spare memory chip. The system selectively transmits the configuration code to shift registers for a memory read driver. Therefore, the system independently shifts data written to the memory inputs and data read from the memory outputs.
    • 存储器重新配置系统通过在缺陷芯片周围移动数据来在系统操作期间将备用芯片动态地配置到存储器中。 数据在整个存储器芯片周围的移位允许系统校正位,寻址和控制芯片内的错误或故障。 当系统检测到错误或以其他方式启动存储器重新配置时,它将配置代码发送到存储器写入驱动器的移位寄存器。 移位寄存器响应于配置代码移位写入数据,使得数据被有效地围绕特定存储器芯片移位到备用存储器芯片中。 系统选择性地将配置代码发送到用于存储器读取驱动器的移位寄存器。 因此,系统独立地将写入存储器输入的数据和从存储器输出读取的数据进行移位。
