ADVANTEST
T5377 Automated
The ADVANTEST T5377 is an automated memory test system capable of simultaneously testing up to 256 DUTs per system at test speeds of up to 143/286 MHz in DDR mode. The T5377 is designed for wafer test of DRAMs and package test of Flash memory.[1]
What it is
The ADVANTEST T5377 is an automated test system designed for semiconductor memory devices.[1]
The T5377 is a memory tester that provides solutions for wafer test of DRAMs and package test of Flash memory.[1]
The system is fully compatible with its predecessor, the ADVANTEST T5375, allowing test programs and probe cards to be reused without modification.[1]
How it works
The T5377 is fitted with dual test heads, enabling it to test at two stations simultaneously.[1]
The system can simultaneously test up to 256 devices under test per system at test speeds of up to 143 or 286 MHz in DDR mode.[1]
The T5377 can capture fail data for large capacity memory devices, supporting functional testing and redundancy analysis for high density memory devices.[1]
An optional MRA4 ev2 redundancy analyzer can be selected for greater flexibility and efficiency in memory repair analysis.[1]
The system includes pattern generation via ALPG with configurable address and data lines, and supports parametric test units and programmable power supplies.[1]
Where it fits in the process flow
The system supports both wafer-level testing of DRAMs and final package testing of Flash memory devices.[1]
Applications
The T5377 is used for testing DRAM, SDRAM, DDR devices, SRAM, Flash memories, Direct RDRAM, EPROM, and Masked ROM.[1]
The system targets high-volume production testing of memory devices, with its simultaneous test capability improving throughput.[1]
