    • Memory devices, memory controllers, methods, and systems are provided, such as methods for masking the row cycle latency time of a memory array. In one embodiment, a memory device that is configurable to operate in full or reduced density modes is provided. In a reduced density mode, certain banks within the memory array function as duplicate memory banks associated with an addressable memory bank. Write operations performed in the reduced density mode may write a data segment to an addressed memory bank as well as its associated duplicate banks. When repeated read requests are issued for the data segment, the read requests may be interleaved between the addressed bank and its duplicate banks, thereby masking the row cycle time of each physical bank. That is, the interval between each read out of the data segment from the memory array will appear to be less than the row cycle time.
    • 提供存储器件,存储器控制器,方法和系统,例如用于掩蔽存储器阵列的行周期等待时间的方法。 在一个实施例中,提供了可配置为以全密度或低密度模式操作的存储器件。 在减密密度模式中,存储器阵列内的某些存储体用作与可寻址存储体相关联的重复存储体。 以减小密度模式执行的写入操作可以将数据段写入寻址的存储体以及其相关的重复存储体。 当对于数据段发出重复的读请求时,读请求可以在寻址的存储体和其重复存储体之间进行交织,由此屏蔽每个物理存储体的行周期时间。 也就是说,每个从存储器阵列读出的数据段之间的间隔将看起来小于行周期时间。

    • Memory modules and methods for fabricating and implementing memory modules wherein unique device parameters corresponding to specific memory devices on the memory modules are accessed from a database such that the device parameters may be implemented to improve system performance. The device parameters may include sizes, speeds, operating voltages, or timing parameters of the memory modules. Memory modules comprising a number of volatile memory devices may be fabricated. Device parameters corresponding to the specific memory devices on the memory module may be stored in a database and accessed during fabrication or during implementation of the memory modules in a system. System performance may be optimized by implementing the unique device parameters corresponding to the specific memory devices on the memory modules.

    • Memories, buffered write command circuits, and methods for executing memory commands in a memory. In some embodiments, read commands that are received after write commands are executed internally prior to executing the earlier received write commands. Write commands are buffered so that the commands can be executed upon completion of the later received read command. One example of a buffered write command circuit includes a write command buffer to buffer write commands and propagate buffered write commands therethrough in response to a clock signal and further includes write command buffer logic. The write command buffer logic generates an active clock signal to propagate the buffered write commands through the write command buffer for execution, suspends the active clock signal in response to receiving a read command after the write command is received, and restarts the active clock upon completion of the later received read command.
    • 存储器,缓冲写入命令电路和用于在存储器中执行存储器命令的方法。 在一些实施例中,在写入命令之后接收的读取命令在执行先前接收的写入命令之前在内部执行。 写入命令被缓冲,以便在完成稍后接收的读取命令时可以执行命令。 缓冲写入命令电路的一个示例包括写入命令缓冲器以缓冲写入命令并且响应于时钟信号传播缓冲的写入命令,并且还包括写入命令缓冲器逻辑。 写命令缓冲器逻辑产生一个活动时钟信号,通过写命令缓冲区来传送缓冲的写入命令,以便执行,响应在接收到写入命令之后接收到一个读取命令,暂停有效的时钟信号,并在完成后重新启动激活的时钟 的后来收到的read命令。
