It is integrated with Processor. Also called Cache Memory.
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.

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.
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.
To install laptop memory, you will need to first consult the instruction manual. Afterwards, you can buy the memory chip, open up the laptop and then place the memory chip inside.
why not??? but it would have to be a pretty small chip!!!

60 gigs in a memory chip is a HUGE amount. (As far as I know, no one builds a 60 gig memory chip). Conversely, a 60 gig hard drive is pretty minimal by current standards.
