Apple A9 APL0898 RAM

A system-on-chip integrates multiple components onto a single chip, a prominent component being the Random Access Memory, or RAM. Since SoC is the condensed version of a CPU on a chip, a trade-off between maximizing the RAM capacity while reducing its size is necessary. Since the SoC is primarily incorporated into mobile phones, the performance is directly influenced by the Apple A9 APL0898 RAM present on the chipset. So, if you are about to buy any of these chipset, its inevitable to explore Apple A9 APL0898 Processor. Inside the Apple A9 APL0898 memory, its RAM is used to store information of running programs in your device and therefore is the fastest memory on the device. But, memory in RAM is lost once the device loses power or is turned off.

Apple A9 APL0898 Cache

Apparently, the major breakthrough for memory devices occurred in the 1970s, after the inclusion of solid-state memory into integrated circuits. This invention used very small transistors, facilitating the storage of a lot more information into a very tiny area on the circuit board. Cache is the memory that stores the frequently, or recently, accessed locations of ROM or device memory. The next time any location has to be accessed, it is first checked into the cache and thereby fastens the retrieval. Cache differs from RAM, where unlike RAM which is volatile, cache can store the data for indefinite amount of time. Apple A9 APL0898 memory is classified further as L1 cache, L2 cache and L3 cache.

Apple A9 APL0898 L1 Cache

Apple A9 APL0898 Cache is clasified as L1 cache , L2cache etc., according to the priority of data storage and retrieval. L1 cache stands for Level 1 cache. Although it is lesser in size than L2 and L3 cache, the speed of data access in higher than the other cache. Generally, L1 cache is in the order of few hundred kBs, while L2 and L3 cache are of few MBs. This chipsets incorporates 64 KB kB of L1 cache,
