    • A method and system for increasing the lifespan of a flash memory device by selectively erasing sub-blocks of a memory block. Each physical memory block of the flash memory device is dividable into at least two logical sub-blocks, where each of the at least two logical sub-blocks is erasable. Therefore, only the data of the logical sub-block is erased and reprogrammed while unmodified data in the other logical sub-block avoids unnecessary program/erase cycles. The logical sub-blocks to be erased are dynamically configurable in size and location within the block. A wear leveling algorithm is used for distributing data throughout the physical and logical sub-blocks of the memory array to maximize the lifespan of the physical blocks during programming and data modification operations.
    • 一种用于通过选择性地擦除存储器块的子块来增加闪存器件的寿命的方法和系统。 闪速存储器件的每个物理存储器块可被分割成至少两个逻辑子块,其中至少两个逻辑子块中的每个逻辑子块是可擦除的。 因此,只有逻辑子块的数据被擦除并重新编程,而另一个逻辑子块中的未修改数据避免了不必要的编程/擦除周期。 要擦除的逻辑子块可在块内的大小和位置上动态配置。 磨损均衡算法用于在存储器阵列的整个物理和逻辑子块中分布数据,以在编程和数据修改操作期间最大化物理块的寿命。

    • A configurable memory subsystem includes a memory module with a circuit board having a first and a second memory-containing device (MCD) pair mounted thereto. Each MCD pair has a first MCD in communication with a second MCD. Each MCD has an input port, an output port, and a memory each communicating with a bridge. In response to a command, the bridge transfers at least one of a portion of a data packet from the input port to the output port or to the memory, or transfers a portion of a memory packet from the memory to the output port. A loop-back device receives the command and the data packet form the first MCD pair and transmits the command and data packet to the second MCD pair.
    • 可配置存储器子系统包括具有电路板的存储器模块,该电路板具有安装在其上的第一和第二存储器容纳装置(MCD)对。 每个MCD对具有与第二MCD通信的第一MCD。 每个MCD都有一个输入端口,一个输出端口和一个与桥连通的存储器。 响应于命令,桥将数据分组的一部分中的至少一个从输入端口传送到输出端口或存储器,或者将存储器分组的一部分从存储器传送到输出端口。 环回装置从第一MCD对接收命令和数据包,并将命令和数据包发送到第二MCD对。
