KGD : Known Good Die (KGD offered provides the same level of quality as package products)

 

Overview

SDRAM

SDRAM(SynchronousDRAM) is a synchronous type of DRAM. Over 25 years of experience in developing and supplying DRAM products has allowed us to meet all requirements by automotive manufacturers for quality and reliability.
And Ta(max)=105°C for automotive grade are available.

Features

Features1
Continuous, stable supply

We are focused on supplying legacy DRAM such as FP/EDO and SDRAM due to the demand in the market for stable, high quality supply.

Production is performed in Japan and at overseas facilities, ensuring uninterrupted supply around the world.

In addition to the broad lineup, customized products are available to meet specific requirements.

 
Features2
Improved waveform quality with output drivability control

PC100-compatible output drivers in consumer equipment and automotive systems were designed for multiple DRAMs connected in parallel. This requires a damping resistor and waveform adjustment.

LAPIS Semiconductor offers 3 models that enable 3-stage output drivability adjustment based on an extended mode register.

Waveform quality can be optimized by controlling output drivability, eliminating the need for a damping resistor and EMI countermeasures, reducing both component count and costs.

Features3
Automotive grade reliability
Automotive grade reliability

Over 25 years of experience in developing and supplying DRAM products has allowed us to meet all requirements by automotive manufacturers for quality, reliability, support, supply, and traceability.

LAPIS Semiconductor products meet automotive requirements for incidental and initial failure rates.

Features4
Superior electrical conductivity Cu(Copper) frame
Cu(Copper) frame

A lineup of products with a Cu frame is utilized for high connection reliability.

Features5
Support Policy
Support Policy
  • The chip traceability is guaranteed. Lot No., wafer No., and position on the wafer are recorded.
  • Simulation models are provided. Verilog (NC Verilog/VerilogXL)
  • IBIS model
Features6
KGD (Known Good Die) guaranteed for chip products
KGD保証

We offer KGD DRAM chips in the form of wafers, featuring quality equivalent to package products, for use in SiP (System in Package) applications.

*All SDRAM products for SiP utilize custom part numbers.
