As a professional Etron Yuchuang agent,EM638325BK,which is promoted by our company,is a high-performance and high-speed DRAM chip.It uses advanced CMOS technology to build a storage capacity of 64Mb.With its stable performance and flexible adaptation characteristics,it is widely suitable for various high-bandwidth and high-stability electronic equipment storage scenarios,and it is a common synchronous dynamic storage chip in industrial and consumer electronics fields.
1.Overview of Etron Yuchuang high-speed DRAM chip.
This DRAM chip adopts four channels of 512K×32 memory architecture,and the single memory cell is in a regular layout of 2048 rows×256 columns×32 bits.With the standard synchronous clock interface,all signals are synchronized by the rising edge of the clock,effectively avoiding the problem of data transmission delay.The read-write operation of DRAM chip equipment supports burst access mode,and the read-write process can be started by activating the instruction of Bank.The operation process is standardized and the response efficiency is excellent,which adapts to the operation requirements of various embedded systems.
2.Functional configuration of Etron Yuchuang high-speed DRAM chip.
EM638325BK high-speed DRAM chip supports diversified programmable debugging modes,can flexibly set multi-specification burst lengths of 1,2,4,8 and the whole page,and is compatible with sequential and staggered burst types,with burst termination and write-once functions to adapt to the operating parameter requirements of different devices.At the same time,DRAM chip is equipped with triple functions of automatic pre-charge,automatic refresh and self-refresh,and the specification of 4096 refresh cycles/64 milliseconds ensures stable data storage,which can prevent data loss and confusion.The chip supports 2/3-speed CAS delay switching,and users can adjust it independently according to the working conditions of the equipment to maximize the overall running performance of the equipment.
3.Performance and adaptability of Etron Yuchuang high-speed DRAM chip.
The measured access speed of the DRAM chip can reach 5.0-5.4ns,and it supports multi-gear high-speed clock frequencies of 200MHz,166MHz and 143MHz.The built-in pipeline architecture greatly improves the data throughput efficiency.The DRAM chip adopts the standard working voltage of 3.3V,and the voltage fluctuation fault tolerance range is 0.3V.With 90-ball FBGA package and LVTTL interface,it supports the precise control of DQM0-3 single byte.Industrial-grade 0℃-70℃wide temperature working design enables it to stably adapt to industrial control equipment,intelligent terminals,consumer electronics and other scenarios,with high compatibility and durability.
