The iPhone 11 is a smartphone developed and marketed by Apple.It is the thirteenth generation of iPhone, succeeding the iPhone XR, and was unveiled on September 10, 2019, alongside the higher-end iPhone 11 Pro at the Steve Jobs Theater in Apple Park, Cupertino, by Apple CEO Tim Cook.
FPM, EDO, SDR, and RDRAM memory was not commonly installed in a dual-channel configuration. DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given ...
The top and side of an iPhone 5S, externally identical to the SE (2016).From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The touchscreen on the iPhone has increased in size several times over the years, from 3.5 inches on the original iPhone to iPhone 4S, to the current 6.1 and 6.9 inches on the iPhone 16 and 16 Pro Max series.

The term sides would also be confusing because it incorrectly suggests the physical placement of chips on the module. All ranks are connected to the same memory bus (address + data). The chip select signal is used to issue commands to specific rank. Adding modules to the single memory bus creates additional electrical load on its drivers.
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.
