The Powerful LPDDR4 & LPDDR3 IC Test System

Essential Features with Enhanced Options

The TurboCATS III-3200STPIC LPDDR4 and LPDDR3 IC test system brings to the memory semiconductor industry a unique combination of performance and affordability along with an upgradeable system design. 128 devices can be tested in parallel in order to provide a faster production. An optional handler interface allows the test system to communicate to a handler which perform device sorting and binning after testing.

Customization Options

• LPDDR4 - supports speeds up to 3200Mbps
• LPDDR3 - supports speeds up to 1866Mbps
• Capable of testing up to 128 LPDDR4 and LPDDR3 devices in parallel
• Number of sites for the chassis can be adjusted according to customers' request
• Supports None-Cable HiFix that can be integrated with a selection of handlers' interfaces

TurboCATS is pioneering a high performance None-Cable HiFix unit integrated with our high performance TCIII-3200STDRIC (DDR4/ DDR3 IC) or TCIII-3200STLPIC (LPDDR4/ LPDDR3 IC) test system. The test system is connected to the IC socket board via TurboCATS' None-Cable HiFix unit, which is cableless to maximize the performance of signal transmission. This ensures that the test system is easy to maintain since the user no longer needs to go through hundreds of cable wires within the unit.

What is None-Cable HiFix?

Speed, signal integrity and costs are the challenges for building a HiFix unit integrated to the automated handler system. The conventional HiFix comes with a large bundle of long cable wires to connect with the HiFix and IC socket boards. It causes signal degradation and timing jitter due to the impedance mismatching, conductor losses, radiation effects, etc. It is also difficult to maintain and repair due to the need to go through a large bundle of cable wires.

Multi-Site Networking

Solutions for your connected testing

The TCIII-3200STLPIC (LPDDR4/ LPDDR3) IC test system can be networked so the user can test up to 128 devices using one PC to control the entire operation. This gives the customer greater flexibility in terms of increasing testing capacity on an as-needed basis.

GUI Failure Analysis

Graphical Identification of Failed DQs' Locations

Represents the failed DQ pins' locations graphically. The software uses a graphical display to show the test failures at the hardware level: If the IC fails during the test, there would be indications (displayed in RED) marking the failed pin(s) and signal(s).

Address/ Data Logging

Error logging can analyze failures by using address and data information.

Bit Failure Mapping

A tool that helps the user find the failed DQ bits in the RAM by spotting and displaying the corresponding row and column addresses.

Address Scramble

Address Scramble allows users to redefine an address line logic.

Data Scramble

Data Scramble is based on the input addresses, which determine write data or /data.

Shmoo Plot

A two-dimensional diagram that shows the status of the DQ bits of Memory ICs varying over a range of the user's selected parameters (timing and input voltage level).

Script Code Function (optional)

Script Code Debugger

The customer can use a script programming language to create a customized test pattern. It also supports up to maximum 2048 data patterns. The Script Code function also serves as a powerful compiler/ debug tool. It contains a built-in compiler and debugger for Script Code programming that allows the user to monitor the timing waveform of the programming algorithm along with the timing bus transactions. This is all accomplished with the Signal Tap tool.
