Storage chips are mainly used for data storage. They can be non -prone, such as flash memory, which can save data even after the power supply is closed;Or easy to lose, such as dynamic random access memory (DRAM), data will be lost after power off. The main goal of the storage chip is to provide high -speed, high -density and low -cost data storage solutions.
Logical chips are integrated circuits for performing logical operations and processing tasks. Programmable logic devices (PLD), such as on -site programming door array (FPGA) and complex programmable logic devices (CPLD), are the category of logical chips. Logical chip is used to perform specific computing tasks, not just store data.
Exterior
1.The type of packaging:
Storage chips:Common in the forms of SO-DIMM, SSD, Microsd and other forms, mostly used in memory bar or memory cards. Logic chip: Common packaging of PGA, BGA, etc., mostly used for CPU, FPGA, etc.
2.Physical size:
Storage chip:Dimensions (such as NAND or DRAM) and capacity. Logic chip: The size is usually proportional to the complexity, and the processor is larger than the simple logic chip.
structure
1.Crystal tube layout:Storage chip: Optimize to achieve dense layout for storage cells. Logic chip: The layout of the transistor is more complicated to support a variety of logical functions.
2.Circuit design:Storage chip: Simple design, high repetitive storage unit array. Logic chip: complex logic doors and circuit design for complex operations.
Manifestations
1.Data processing method:Storage chip: linear and sequence, suitable for fast reading and writing operations. Logic chip: parallel and multi -tasking, suitable for complex logical operations and decisions.
2.Speed and performance storage chip:speed is limited by the reading and writing cycle and storage medium. Logic chip: execution speed is affected by chip design and logic complexity.
application
1.Application industry:Storage chips: Widely used in consumer electronics, servers, data centers and mobile devices. Logic chip: used to computing equipment, industrial automation, automotive electronics and communication networks.
2.Functional use storage chips:for data retention, such as document storage, multimedia file retention, etc. Logic chip: used for data processing, such as calculation, data transmission control, signal conversion, etc.
When choosing storage and logical chips, you need to consider the following aspects:
Design requirements: Learn how much storage space you need and which type of logical operations need to be performed.
Performance specifications: Consider the required processing speed, bandwidth, storage capacity and power consumption.
Cost benefits: Based on the design budget, weigh the cost of different types and specifications chips.
Scalability: Considering possible future upgrades and expansion needs.
Ecosystem: Make sure the chip selected has good support and resources, such as development tools and libraries.
Supply chain reliability: Considering the stability of the supplier and the availability of the chip.
Technical compatibility: Confirm that the selected chip can be compatible with existing hardware and software systems.
In short, storage chips and logical chips are different in many ways, from physical structure to application purposes. When choosing, comprehensive considerations should be made according to project needs, performance requirements, and budget constraints. During the development process, storage and logical chips are usually cooperated with each other to achieve the best system performance.
