Method and system for facilitating fast wake-up of a flash memory system

A memory system comprising:

• (a) a memory module including a nonvolatile memory;
• and
• (b) a host, of said memory module, that participates in managing said nonvolatile memory by steps including:
• (i) storing in said first nonvolatile memory at least a portion of a management table whose contents indicate a state of the memory system at a first point in time,
• (ii) storing in said first nonvolatile memory a future information data structure including a plurality of records related to events of the memory system expected to occur subsequent to said storing of said future information data structure, and
• (iii) at a second point in time subsequent to said storing of said future information data structure, handling a said event in accordance with said future information data structure.

A memory module comprising:

• (a) a first nonvolatile memory;
• and
• (b) a controller of said nonvolatile memory that is operative to wake up the memory module by steps including
• (i) reading, from said first nonvolatile memory, at least a portion of a management table describing a state of the memory module at a point in time prior to the waking up;
• (ii) reading, from said nonvolatile memory, a future information data structure including a plurality of records related to events expected to occur subsequent to a storing of said future information data structure;
• and
• (iii) updating said management table in accordance with at least one record of said future information data structure.

A computer-readable storage medium having computer-readable code embodied therein for maintaining data structures of a memory system in accordance with events of the system, the computer-readable code comprising:

• (a) program code for storing, in a nonvolatile memory of the memory system, at least a portion of a management table whose contents indicate a state of the memory system at a first point in time;
• (b) program code for storing in said nonvolatile memory a future information data structure including a plurality of records related to events of the memory system expected to occur subsequent to a said storing of said information data structure;
