TCIII-1600ST DIMM Tester

4 Powerful DC functions for today's OEM

High-end ATE's are designed to detect functional and AC/DC parametric failures but cannot identify or pinpoint potential in-system failures. Most in-system failures are a result of functional and timing compatibility issues that are generated by the system chipset. Many in-system device failures occur during system boot up or during performance of a specific operation within a given system.

 

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

To effectively deal with functional testing as well as 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.)

  1. Functional and parametric testing
  2. In-System testing utilizing motherboards

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

Supports 16 DUT's in parallel testing.

Designed for Performance & Affordability

To assist manufacturers in their efforts to control costs, Triad Spectrum proudly introduces the TCIII-1600ST multi-site test system. Device characterization and failure analysis tools such as Shmoo plotting and address/ data error logging are included on the TCIII-1600ST to assist engineers in their design/debug processes. An optional hot temperature chamber is available to detect marginal timing and cell storage failures that often occur in high temperature system environments. The chamber is user programmable and can be set at temperatures ranging from 32°C to 85°C with 2°C resolution.

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 insure that proper values are used in all places as well as insuring that they are 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

4. VREFA / VERFQ

Voltage ref short detection including programmable VREFCA and VREFDQ.

 

Combination of Failures

  1. Functional Failure: Cell stuck-at, coupling, neighborhood sensitivity and software error faults.
  2. Parametric Failure: (AC) Speed timing vs. Vdd threshold, (DC) Leakage and Idd's.
  3. In-System Failure: System chipset functional, timing sensitivities and specific application.
  4. Hot-Temperature Failure: System high temperature environment.
 

Bit Failure Mapping

Bit failure mapping is a tool that helps users to find and display the failed DQ bits in the RAM. The corresponding row and column address of the failed DQ bits will be spotted and displayed for the user with the aid of the 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.


 

Optional Script Code Function

Traditional test systems provide the user with a variety of AC test patterns to use in their testing process. If a customer wanted the capability to generate a proprietary test pattern, they had to purchase a high-end automated test system. For most companies this is cost prohibitive and not a viable option.

Triad Spectrum has once again listened to what the customers are saying and is proud to offer 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 serves as a powerful compiler/debug tool. It 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.

The new pattern is then imported into the test list and gives the customer a customized pattern with AC (tSU, tWD, tSAC, tRCD, tCL, tAL, tWR, tRP, tRC, tREF, tRFC, etc.) and DC (Vdd, Vref) parameters for testing their product. In addition to the above, the customer can also create a motherboard test pattern algorithm using the "Script Code" function. The TurboCATS III-1600ST performs the test with no wait states in the operating system.

Utilizing the "Script Code" function gives the customer a high degree of flexibility in terms of timing bus programming for creating unique Read and Write programmingtransactions under best and worse case AC parameters. This can also be used to create a no-wait state bus transaction in the Read to Write cycle.

 

NEW Powerful Integration

  1. Script Code Function
    • Older model Triad Spectrum test systems provided a wide variety of AC test patterns but did not allow the user to generate a proprietary test pattern. The new TCIII-1600ST offers the "Script Code" feature. This will let the end user program proprietary test patterns.

    • Utilizing the script programming language, the customer can create a customized test pattern and then use the Script Code pattern generation compiler to compile and generate the new test pattern. The new pattern is then imported into the test list with AC (tSU, tWD, tRCD, tCL, tAL, tWR,tRP, tRC, tRFC, etc) and DC (Vdd, Vref) parameters for customized testing.

  2. Faster Than Motherboard Test
    • The end user can also create motherboard test pattern algorithms, utilizing the Script Code function and then use this in addition to the programmable AC and DC parameters. Test patterns in the TC III-1600ST perform much faster than the stand alone Motherboard test because there are no "wait states" in the operating systems.

  3. Enhanced Timing Bus
    • Script Code programming gives the end user a great deal of flexibility in programming the timing bus to create a unique Read and Write bus transaction under best and worst case AC parameters. In addition, a "no wait" state bus transaction can be created in the Read to Write cycle.

  4. Powerful Debug/Compiler Tool
    • A built in compiler and debugger environment is in the Script Code programming. This allows the user to monitor the timing waveform of the programming algorithm and the timing bus transactions under the Signal Tap tool.
