Dynamically centered setup-time and hold-time window

An apparatus, comprising:

• a data storage device to provide stored data;
• and
• a controller coupled to said data storage device, said controller being adapted to detect a movement of an access window defined by a predetermined setup-time limit and a predetermined hold-time limit and dynamically centers said access window between said setup-time and said hold-time limit in response to said movement of said access window.

A circuit for accessing memory, comprising:

• a controller coupled to said memory, said controller being adapted to detect a movement of an access window defined by a predeter mined setup-time limit and a predetermined hold-time limit and to dynamically center said access window between said setup-time limit and said hold-time limit in response to said movement of said access window.

A system board, comprising:

• a first device comprising a memory location for storing data and a dynamic access window unit, said dynamic access window unit being adapted to detect a movement of an access window defined by a predetermined setup-time limit and a predetermined hold-time limit and to dynamically center said access window between said setup-time and said hold-time limits in response to said movement of said access window;
• and
• a second device operatively coupled to said first device, said second device to access data from said first device based upon said access window.

A computer system, comprising:

• a first device comprising a memory location for storing data and a dynamic access window unit, said dynamic access window unit being adapted to detect a movement of an access window defined by a predetermined setup-time limit and a predetermined hold-time limit and to dynamically center said access window between said setup-time limit and said hold-time limit in response to said movement of said access window;
• and
• a second device operatively coupled to said first device, said second device to access data from said first device based upon said access window.

A memory device for providing memory access, said memory device comprising a controller adapted to detect a movement of an access window defined by a predetermined setup-time limit and a predetermined hold-time limit and to dynamically center said access window between said setup-time limit and said hold-time limit in response to said movement of said access window.
