PPT-Flash Storage and IO Operation

Explain the limitations of flash memory Define wear leveling Define the term IO Transaction Define the terms synchronous bus and asynchronous interconnect Explain the difference between polling and interrupts. Adaptive Flash is based on CASL Nimbles patented CacheAccelerated Sequential Layout architecture and InfoSight its data sciencesbased approach to the storage lifecycle CASL allows performance and capacity to be scaled seamlessly and independently In Presentation By: .

What are flash chips, aka SSDs?. Flash chips are designed to store one or more bits in a single transistor. single-level cell (SLC) flash, only a single bit is stored within a transistor (i.e., 1 or 0). Prof. Onur Mutlu.
