    • A method for providing indeterminate read data latency in a memory system. The method includes determining if a local data packet has been received and storing it into a buffer device. The method also includes determining if the buffer device contains a data packet and determining if an upstream driver for transmitting data packets to a memory controller via an upstream channel is idle, and in response thereto the data packet is transmitted to the upstream driver. The method further includes determining if an upstream data packet has been received and the upstream driver is not idle, then the upstream data packet is stored into the buffer device. The upstream data packet is selectively transmitted to the upstream driver. If the upstream driver is not idle, then any data packets in progress are continued being transmitted to the upstream driver.
    • 一种用于在存储器系统中提供不确定的读取数据延迟的方法。 该方法包括确定本地数据分组是否已被接收并将其存储到缓冲设备中。 该方法还包括确定缓冲器装置是否包含数据包,并确定是否经由上游信道将数据包发送到存储器控制器的上游驱动器是空闲的,并且响应于此数据包被发送到上游驱动器。 该方法还包括确定是否已经接收到上游数据分组,并且上游驱动器不空闲,则上游数据分组被存储到缓冲设备中。 上游数据包被选择性地发送到上游驱动器。 如果上游驱动程序不空闲,那么正在进行的任何数据分组都将继续传输到上游驱动程序。

    • A memory system having a memory element chip (DRAM) and a memory controller chips having a plurality of drivers and receivers and latches for transferred data. For writes clocks, write data and write for CRC (cyclic redundancy checks) is transferred to the DRAM from the memory controller and latched for error checking. The reads are clocked and the read data is received and transferred to a read data latch with also receives a clocked read strobe for verification of data integrity from DRAM. Each chip has a bi-functional pin that acts as a shared CRC pin during write and acts as a shared strobe pin during READ. Data transfers with the CRC signal and DQS signal are transferred across two paths CRC0/DQS and CRC1/DQS1. One could also transfer the CRC signal across one path with only the CRC0/DQS signal. Read operations have no CRC, and have no need for CRC because transfer errors during read can be detected by memory error correction coding (ECC). Write data provides source synchronous I/O data to said memory element chip needed for modem high speed memory communications.
    • 具有存储元件芯片(DRAM)的存储器系统和具有用于传送数据的多个驱动器和接收器以及锁存器的存储器控​​制器芯片。 对于写时钟,写入数据和写入CRC(循环冗余校验)从存储器控制器传送到DRAM,并锁存进行错误检查。 读取被计时,并且读取的数据被接收并被传送到读取数据锁存器,同时还接收用于从DRAM确认数据完整性的时钟读选通脉冲。 每个芯片都有一个双功能引脚,在写入期间充当共享的CRC引脚,并在读取期间充当共享的选通引脚。 具有CRC信号和DQS信号的数据传输通过两个路径CRC0 / DQS和CRC1 / DQS1传送。 也可以通过CRC0 / DQS信号在一个路径上传送CRC信号。 读操作没有CRC,并且不需要CRC,因为可以通过存储器纠错编码(ECC)来检测读取期间的传输错误。 写入数据将源同步I / O数据提供给调制解调器高速存储器通信所需的所述存储器元件芯片。
