TSE 2002 Serial Presence Detect (SPD) with Thermal Sensor in Process

Arlington, VA - September 4, 2007 - Temperatures are running hot in the computing
industry as engineers struggle with rising thermal profiles for computer memory while
form factors are getting ever smaller. JEDEC has given some relief to system
designers with committee approval of the TSE2002 Serial Presence Detect (SPD) with
Thermal Sensor.

The TSE2002 device incorporates the standard functions of the SPD, an EEPROM
found on all JEDEC reference designs to make the module configuration and
performance specifications readable over an SMBus, with a thermal sensing function
accurate to within a half degree Celsius. It is pin compatible with the standard EE1002
SPD and can be incorporated immediately into existing module designs.

The TSE2002 also includes thermal trip points and an interrupt output pin that can be
used to alert the system when critical thermal thresholds are crossed, giving the system
time to adjust conditions such as by increasing the speed of cooling fans, or to alert
system operators of potential error conditions before they occur. Since using the
interrupt output may require hardware changes, these thermal trip points are also
available by polling the SMBus interface.

"TSE2002 devices are available now from multiple suppliers who contributed to the
development of the JEDEC specification," said Bill Gervasi, chairman of the SPD Task
Group. "Incorporation of the TSE2002 into future JEDEC modules is already
underway."

The TSE2002 specification is expected to complete the JEDEC approval process by
mid-November 2007.

JEDEC is the leading developer of standards for the solid-state industry. Almost 3100 participants, appointed by
some 290 companies work together in 50 JEDEC committees to meet the needs of every segment of the industry,
manufacturers and consumers alike. The publications and standards that they generate are accepted throughout
the world. All JEDEC standards are available online, at no charge. More information is available at
