摘要： A method and system for balancing host write operations and cache flushing is disclosed. The method may include steps of determining an available capacity in a cache storage portion of a self-caching storage device, determining a ratio of cache flushing steps to host write commands if the available capacity is below a desired threshold and interleaving cache flushing steps with host write commands to achieve the ratio. The cache flushing steps may be executed by maintaining a storage device busy status after executing a host write command and utilizing this additional time to copy a portion of the data from the cache storage into the main storage. The system may include a cache storage, a main storage and a controller configured to determine and execute a ratio of cache flushing steps to host write commands by executing cache flushing steps while maintaining a busy status after a host write command.

摘要： Methods, apparatus and computer medium for enforcing one or more cache management policies are disclosed herein. In some embodiments, a flash memory of a storage device includes a plurality of flash memory dies each flash memory die including a respective cache storage area and a respective main storage area. A determination is made, for data that is received from an external host device to which main storage area the received data is addressed thereby specifying one of the plurality of flash memory dies as a target die for the received data. Whenever the received data is written into a cache storage area before being written into a main storage area, the received data is written into the cache storage area of the specified target die.
摘要翻译：本文公开了用于执行一个或多个缓存管理策略的方法，装置和计算机介质。在一些实施例中，存储设备的闪速存储器包括多个闪速存储器管芯，每个闪速存储器管芯包括相应的缓存存储区域和相应的主存储区域。对于从接收到的数据被存储到主存储区域的外部主机设备接收的数据进行确定，从而将多个闪速存储器管芯之一指定为接收数据的目标管芯。无论何时在被写入主存储区域之前将接收的数据写入高速缓存存储区域中，将接收的数据写入指定目标管芯的高速缓存存储区域中。

摘要： A host may initialize itself faster by enabling an associated storage device to respond to host access commands under specified conditions before the storage device has completed its own initialization. Embodiments of the invention include a storage device, a controller, a method of servicing commands, and a method of using a host that sends access commands to a storage device. Access commands to a flash memory use logical addresses to reference the memory contents. A controller translates the logical addresses to physical addresses using a mapping table that the controller constructs in volatile memory during initialization based on data retrieved from the flash memory. An access command satisfying a predefined condition is serviced before the controller completes the construction of the mapping table.
摘要翻译：在存储设备完成其自己的初始化之前，通过使相关联的存储设备能够在指定条件下响应主机访问命令，主机可以更快地初始化自身。本发明的实施例包括存储设备，控制器，服务命令的方法以及使用向存储设备发送访问命令的主机的方法。对闪存的访问命令使用逻辑地址来引用存储器内容。控制器使用映射表将逻辑地址转换为物理地址，控制器在初始化期间基于从闪速存储器检索的数据在易失性存储器中构造。在控制器完成映射表的构建之前，对满足预定条件的访问命令进行处理。
