Notes :
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.

Notes :
1. This is to advise Samsung customers that, in accordance with certain terms of an agreement, Samsung is prohibited from
selling any DRAM products configured in "Multi-Die Plastic" format for use as components in general and scientific computers,
such as mainframes, servers, work stations or desk top personal computers (hereinafter "Prohibited Computer Use").
Applications such as mobile, including cell phones, telecom, including televisions and display monitors, or non-desktop
computer systems, including laptops, notebook computers, are, however, permissible. "Multi-Die Plastic" is defined as two or
more DRAM die encapsulated within a single plastic leaded package.
2. Samsung are not designed or manufactured for use in a device or system that is used under circumstance in which human life
is potentially at stake. Please contact to the memory marketing team in samsung electronics when considering the use of
a product contained herein for any specific purpose, such as medical, aerospace, nuclear, military, vehicular or undersea
repeater use.
