Hi,

anyone describe whats the below lines means.

'' memory device containing 64Mbit Pseudo Static Random Access

Memory using a self-refresh DRAM array organized as 4M words by 16 bits.''

Do you understand the difference between dynamic and static memory? ie charge held by a capacitor vs logic state held by several transistors.

4 x 16 = 64

The memory is arranged so each storage location holds 16 bits, there are 4 million (4194304) locations, which are uniquely addressable, in random order.

The device is dynamic, pretending to be a static device, it refreshes (recharges) the storage cell capacitors in the background, with no interaction from the external system.
