TCIII-1600ST DDR1/2/3 & SDRAM DIMM Tester

Next Generation System for DIMM Testing

High-end ATEs are designed to detect functional and AC/DC parametric failures but do not identify or pinpoint potential in-system failures. Most in-system failures caused by functional and timing compatibility issues that are generated by the system chipset. Many in-system device failures occur during system boot up or during the specific testing operation within a given system.

DWith the ability to test 16 modules in parallel and at speeds up to 1600Mbps, the TCIII-1600ST will meet the needs of an engineering group while being the ideal ATE for the production floor as well.

To effectively perform functional testing and in-system compatibility testing, most memory manufacturers incorporate a costly two (2) step testing process as part of their Standard Operating Procedure (S.O.P.).

  • Functional and parametric testing
  • In-System testing utilizing motherboards

One of memory manufacturers' most difficult challenges is finding a cost effective method of testing their products so they can minimize the time to market and field failures/ returns. To facilitate this costly and time consuming process, they must incorporate the two (2) step testing method. Capital expenditures, for the equipment and manpower required to perform this extensive testing, often result in budget overruns for various cost centers.

Script Code Function (optional)

Script Code Debugger

TurboCATS offers a new feature called "Script Code" in its new test system, the TCIII-1600ST. In this new system, the customer can use the script programming language to create a customized test pattern. Once the pattern is created, the "Script Code" pattern generator/compiler is used to compile the code and then generate the new test pattern.

The "Script Code" function also contains a built-in compiler and debugger for the "Script Code" programming, which allows the customer to monitor the timing waveform of the programming algorithm as well as the timing bus transactions. This is all accomplished under the "Signal Tap" tool.

Bit Failure Mapping

Bit failure mapping is a tool that helps users find the failed DQ bits in the RAM. The corresponding row and column addresses the failed DQ bits, which will be displayed conveniently for the user with the aid of diagrams.

The failed Bank is spotted (Figure 1) and then the user can find the location of the failed DQ bit (Figure 2) if the user double-clicks the failed Bank.

Enhanced DC (VSIM & ISVM)

1. Voltage Sense and Current Measurement (VSIM)

This will detect shorts on the signal line as well as detect proper values of resistor packs and discrete resistors to Ensure that proper values are used in all places and properly mounted.

2. Current Sense and Voltage Measurement (ISVM)

A pattern that will detect any open pins on the contacts between test sockets and DIMM's before functional testing begins. This pattern will also detect any open pins on both passive and memory components on the PCB.

3. System Power Short Protection


Voltage ref short detection including programmable VREFCA and VREFDQ.

Heat Chamber (optional)
