US Patent:

Filed:

May 1, 2001

Appl. No.:

09/847154

Inventors:

Binh Pham - Castro Valley CA

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 1314

US Classification:

711167

Abstract:

An apparatus, system, and method for speeding up data transfers while reducing bus contention during repeated consecutive read-write operations. By reducing the length of time during which selected data pulses are driven on the memory bus, a higher percentage of usage of the memory bus may be attained without increasing the likelihood of bus contention and resulting degradation or damage to the memory system. The selected data pulse is preferably the write data pulse driven on the memory bus by the memory controller. A zero bus turnaround protocol may be implemented. The memory controller may include interface circuitry and write control circuitry that outputs an associated control signal to a three-state buffer. The three-state buffer, after being enabled by the associated control signal, drives write data on a data line of a memory bus. The turn-on delay associated with the three-state buffer exceeds the turn-off delay also associated with the three-state buffer.
