1kb=1024 byte is multiply by the total memory which is given to you as bellow:
(1024*2) = 2048 register
When we talk about "chip", memory is taken in bits. So 2K means 2*1024=2048 bits.
So, number of 8 bits register required is 2048/8 = 256 registers.
Registers represent the number of memory locations. A 2K memory chip has 2x1024=2048 memory locations. Hence there are 2048 registers in a 2K memory.

I am not quite sure how significant this is. The reason, however, is that accessing a register, which is part of the CPU, is faster than accessing RAM memory, which is located on a separate chip.I am not quite sure how significant this is.

what is the function of the wr signal on memory chip
On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
2048/128 = number of chips.
Definition: A device for storing digital information that is fabricated by using integrated circuit technology. Also known as integrated-circuit memory; large-scale integrated memory; memory chip; semiconductor storage; transistor memory. Semiconductor memory is an electronic data storage device, often used as computer memory, implemented on a semiconductor-based integrated circuit. Examples of semiconductor memory include non-volatile memory such as Read-only memory (ROM), magnetoresistive random access memory (MRAM), and flash memory. It also includes volatile memory such as static random access memory (SRAM), which relies on several transistors forming a digital flip-flop to store one bit, and dynamic random access memory (DRAM), which uses one capacitor and one transistor to store each bits. Shift registers, processor registers, data buffers and other small digital registers that have no memory address decoding mechanism are not considered as memory. Data is accessed by means of a binary memory address to the memory. If the memory address consists of M bits, the address area consists of two raised by M addresses per chip. Semiconductor memory are manufactured with a certain word length (number of 1-bit cells sharing the same memory address) that power of two, typically M=1, 2, 4 or 8 bit per chip. Consequently, the amount of data stored in each chip is MN2 bits. Possible figures are 1, 2, 4, 8, 16, 32, 64, 128, 256 and 512 bit, kbit, Mbit, Gbit and Tbit, here defined by binary prefixes. By combining several integrated circuits, memory can be arranged for a larger word length and/or address space than what is offered by each chip, often but not necesserily a power of two.
In other words, how do you save temporary data such as data stored in registers r0 to r7 ? The simplest way to use on-chip RAM of the 8051 is to compile your C code with the "--model-small" small memory model option of the SDCC compiler, which tells it to put all variables in on-chip RAM of the 8051.

no
There's no such thing. The iphone does not have a memory chip you can plug in. If you mean internal spare parts then ebay.
