I will have an interview with a company which designs memory. I am kind of confused: memory design engineer deals with analog design or digital design?
Will anyone enlighten me so I can prepare accordingly?
Digital designer today use synthesis tools and RTL description of design. For simulation he uses Verilog or VHDL models. They don't need to know device physics.
RAM designer more close to analog because he used Spice-like simulator and Spice models.
Unlike analog designer he never will run AC analysis. But he should develop and verify Verilog or VHDL model of designed memory. So he should know HDL languages like digital designer.
Hi noviceca
Analog memories do exist
They are used to store a small number of samples (few hundreds) of very fast signals
In the order of the Nano second (1e-9 S).
An example of analog memory is realized by switched capacitors each capacitor will contain the analog value of the signal... This is the write cycle. Then you have the read cycle where each capacitor is read with an adequate Op Amp and appropriate circuit.
Its a mixed signal design. The analog part is the sense amplifier and charge pumps. Though I think there is more of digital design involved in memory design.
