7. If
t
T
is longer than 1 ns, a time (
t
T
– 1) ns has to be added to this parameter.
8. Anytime the Refresh Period has been exceeded, a minimum of two Auto-Refresh (CBR)
commands must be given to “wake-up” the device.
9. Timing is asynchronous. If setup time is not met by rising edge of the clock then the CKE signal
is assumed latched on the next cycle.
10.Self-Refresh Exit is a synchronous operation and begins on the second positive clock edge after
CKE returns high. Self-Refresh Exit is not complete until a time period equal to
t
RC
is satisfied
after the Self Refresh Exit command is registered.
11.This is referenced to the time at which the output achieves the open circuit condition, not to
output voltage levels.
Note: *)
256MByte PC133 modules with place code “-C” indicating Rev. C dies are used as memory
components are fully PC100 2-2-2 backwards compatible, where PC133 modules with place code
“-A” operates as PC100 3-2-2 on a 100 Mhz memory bus.
A serial presence detect storage device - E
2
PROM - is assembled onto the module. Information
about the module configuration, speed, etc. is written into the E
2
PROM device during module
production using a serial presence detect protocol (I

C synchronous 2-wire bus).
