This technology is called phase-change memory (PCM) and can replace flash memory. Flash memory is used frequently in mobile devices, but it is limited in high-end enterprise infrastructure.
IBM staff said that a PCM chip has been developed. Compared with other PCM chips, this product can effectively double the storage capacity of the device, but the error rate is still very low. General PCM chips may have some problems if stored for a long time.
Independent research analyst Klaus Egg Egge said: "The big problem with PCM chips is the level of trust. If you store things for too long, you have to eliminate a lot of mistakes to get back files."
IBM said that the PCM chip is a lower cost, faster and more durable storage, can be used in consumer devices and data center products, IBM may authorize this technology, rather than relying on their own manufacturing PCM, IBM's annual self-licensing technology The business, with revenues of about 1 billion U.S. dollars.
IBM expects that the PCM chips it designed will be applied to products such as servers and cloud storage for about five years. However, it is too early to tell which market PCM is suitable for.
IBM anticipates that PCM can be a bridge across the gap between flash memory and DRAM memory in terms of speed and endurance. Although DRAM PCM speed cannot keep up, the speed of reading and writing data is flash memory. 100 times. PCM is also more durable and has a write cycle of tens of millions of times, more than 30,000 times that of flash memory.
Push Button Switches
The Push Button Switches, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally can be automatically reset. The Push Button Starter Switch is usually used to issue a start or stop command in the circuit to control the turning on and off of electrical coil currents such as electromagnetic starters, connectors, and relays.
The On Off Push Button Switches refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. It is a master control device with a simple structure and a wide range of applications. In the electrical automatic control circuit, used to manually send control signals to control connectors, relays, electromagnetic starters, etc.
This Pushbutton Switches is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in AC and DC voltage below 440V, the current is less than 5A in the control circuit, generally do not directly manipulate the main circuit can also be used in the interconnection circuit. In actual use, in order to prevent desperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like.
The Momentary Push Button Switch could be divided into metal push button switches and LED Light Switches and ordinary snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, lighted symbol type and key type, etc., with single button and double Buttons. Generally, it adopts a water-storage structure, which consists of a button cap, a return spring, a static contact, a moving contact and a casing. It is usually made into a composite type, and has a pair of normally closed contacts and normally open contacts, and some products can pass. The series connection of multiple elements increases the number of contact pairs. There is also a self-contained button that automatically holds the closed position when pressed, and can be turned on only after the power is turned off.
When the Metal Switches is not pressed, the movable contact is connected with the upper stationary contact. The pair of contacts is called a normally closed contact. At this point, the movable contact is disconnected from the following static contact. The pair of contacts is called a normally open contact: the button is pressed, the normally closed contact is open, the normally open contact is closed, and the button is released. Restore the original working state under the action of the return spring
