Unlike previous types of information storage, flash memory is an EEPROM (electronically erasable programmable read-only memory) form of computer memory and thus does not require a energy supply to retain the information. Flash Memory Wave was invented in the early 1980s by Japanese engineer Masuoka Fujio, who was then working at the Toshiba Corporation and who was looking for a technology that would exchange current knowledge-storage media resembling magnetic tapes, floppy disks, and dynamic random-access Memory Wave (DRAM) chips. The title flash was coined by Ariizumi Shoji, a coworker of Masuoka, who said the process of Memory Wave Method erasure, which might erase all the information on a whole chip at one time, was like a camera’s flash. Flash memory consists of a grid that has two transistors, the floating gate and the management gate, at each intersection, separated by an oxide layer that insulates the floating gate.
When the floating gate is linked to the management gate, the 2-transistor cell has a price of 1. To alter the worth of the cell to 0, a voltage is applied to the management gate that pushes electrons through the oxide layer into the floating gate. Storing the electrons within the floating gate permits the flash memory to retain its data when energy is turned off. A voltage is applied to the cell to alter the value again to 1. Flash memory is configured such that giant sections of a chip, referred to as blocks, or even your complete chip might be erased at a time. Portable gadgets reminiscent of digital cameras, smartphones, and MP3 players normally use flash memory. USB drives (additionally referred to as thumb drives and flash drives) and memory playing cards use flash memory to retailer information. As its price turned cheaper in the early 21st century, flash memory also started showing because the laborious disk in laptop computer computers.
With such an enormous and detailed comic guide historical past, it’s hardly shocking that Marvel stuffs their movies with as many callbacks and Easter eggs as potential. The Marvel Cinematic Universe is definitely accessible to these without a shred of comedian knowledge, however the movies additionally reward observant viewers who've more than a passing information of Marvel lore. As one in every of Marvel’s oldest and most popular heroes, Captain America has extra alternative than most characters for obscure references and delightful visual callbacks. With three films dedicated to Cap’s adventures in the MCU launched to date, it’s a great time to look back at every movie within the sequence - The first Avenger, The Winter Soldier, and Civil Struggle - and the varied hidden particulars they comprise. Only probably the most dedicated Cap fan would have seen all of the next Easter eggs. In Civil Struggle, after giving his M.I.T. Tony Stark runs into a girl who’s been waiting for him backstage.
The girl, who calls herself Miriam, accuses Tony of being responsible for her son’s loss of life, as he perished in Sokovia during Ultron’s assault. What you may not have realized is that this woman is performed by Alfre Woodard, who also plays a much more outstanding function in Netflix’s Luke Cage as Mariah Dillard. Typically, actors should not allowed to play two totally different characters in the Marvel Cinematic Universe, so it’s unusual that an exception was made on this case. Perhaps Robert Downey Jr. was ready to drag some strings, as the two actors go approach back, Memory Wave Method having shared the display screen in 1993’s Heart and Souls and 2003’s The Singing Detective. It’s no secret that Bucky Barnes (Sebastian Stan) seems in all three Captain America films, however what it's possible you'll not have seen is that he has a repeated habit of falling in water. The truth is, he does this in every Cap film and every time he does, it represents a big change for him as a character.
