Mobile Examination HW / SW Considerations Pt1
Below are some selected pages discussing ways to create memory storage and access to it from that book which provides, in a nutshell, a useful exemplar how data retention could be created and managed within early electronic telephones. It is worth reading because a mobile phone examiner will see familiar issues that are addressed when considering a methodology for acquiring data from (mobile) devices.

Chip-in-chip . . .
I remember for the 1980 Moscow Olympics, the lighting and audio were controlled by transistor bases "computers". What was fascinating back then the building of slide in-and-out cards. This was revolutionary concept back then, at least for me. A passive backplane that provided the signalling, power and ground, and each card could be pulled out and replaced within an hour!
The cards were just under about 1' x 2'. This modular concept was amazing to me. Within a year I saw these cards collapse in size from enormous PCBs to chips. When the NE555 knockoffs became available "the sky was the limit".
I expect this to continue collapsing, and getting smaller, and more features added.
That which has been is that which will be,
And that which has been done is that which will be done.
So there is nothing new under the sun.
