C.
SCM read and write speeds are over 10 times faster than flash and can support higher IOPS while offering comparable throughput. Furthermore, data access in flash is at the block and page levels, but SCM can be addressed at the bit or word level.
Answer: C
Pagina 210 do material oficial.
Furthermore, data access in flash is at the block and page levels, but SCM can be
addressed at the bit or word level.
Features:
• Non-volatile
• Short access time like DRAM (like is not a same)
• Low cost per bit like disk
• Solid-state, no moving parts
SCM is slower than DRAM but read and write speeds are over 10 times faster than
flash and can support higher IOPS while offering comparable throughput.
A, B and D are wrong
Answer: C
C is correct.
A is WRONG
pg 209 - SCM is slower than DRAM but read and write speeds are over 10 times faster than flash and can support higher IOPS while offering comparable throughput
pg 210 - Furthermore, data access in flash is at the block and page levels, but SCM can be addressed at the bit or word level. This granularity eliminates the need to erase an entire block to program it, and it also simplifies random access.
