overview

Japanese SDRAM maker

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

Features1Continuous, stable supply

We are focused on supplying legacy DRAM such as 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.

Features2Improved waveform quality with output drivability adjustment function

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 Technology 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.

Features3Automotive 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 Technology products meet automotive requirements for incidental and initial failure rates.

Features4Superior electrical conductivity Cu(Copper) frame

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

Features5Support Policy

The chip traceability is guaranteed.Lot No., wafer No., and position on the wafer are recorded.
Simulation models are provided.(IBIS model)

Features6 KGD (Known Good Die) guaranteed for chip products

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.

Applications

LAPIS Technology's SDRAM is used for frame memory,data buffer,work memory, sound buffer,shock proof and so on of various application.
