The iPhone 8 and iPhone 8 Plus are smartphones developed and marketed by Apple Inc. They are the eleventh generation of the iPhone . The iPhone 8 was released on September 22, 2017, succeeding the iPhone 7 and iPhone 7 Plus , respectively.
The Apple A11 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, [6] and manufactured by TSMC. [1] It first appeared in the iPhone 8 and 8 Plus, and iPhone X which were introduced on September 12, 2017. [6]
The third-generation iPhone SE has a similar design to the iPhone 8 and similar internal hardware components to the iPhone 13 series, including the A15 Bionic system-on-chip [10] and 5G connectivity. The third-generation iPhone SE is the last iPhone to feature 4 GB of RAM, as well as 64 GB of internal storage, a Home Button with Touch ID, and ...
Implicitly, it is assumed that the failure of each bit in a word of memory is independent, resulting in improbability of two simultaneous errors. This used to be the case when memory chips were one-bit wide, what was typical in the first half of the 1980s; later developments moved many bits into the same chip.
30-pin SIMM, 256 KB capacity Two 30-pin SIMM slots on an IBM PS/2 Model 50 motherboard. Standard sizes: 256 KB, 1 MB, 4 MB, 16 MB. 30-pin SIMMs have 12 address lines, which can provide a total of 24 address bits. With an 8-bit data width, this leads to an absolute maximum capacity of 16 MB for both parity and non-parity modules (the additional redundancy-bit chip usually doe

Pseudostatic RAM (PSRAM or PSDRAM) is dynamic RAM with built-in refresh and address-control circuitry to make it behave similarly to SRAM. It combines the high density of DRAM with the ease of use of true SRAM. PSRAM (made by Numonyx) is used in the Apple iPhone and other embedded systems. [17] Some DRAM components have a self-refresh standby mode.
