Description The device is CMOS Dynamic RAM organized as 1,048,576 words x 16 bits. It is fabrionly or 3.3V only power supply. Low voltage operation is more suitable to be used on battery backup, portable electronic application. A new refresh feature called " self-refresh " is supported
VG26(V)(S)18160CJ 1,048,576 x 16 - Bit CMOS Dynamic RAM
cated with an advanced submicron CMOS technology and designed to operate from a single 5V
and very slow CBR cycles are being performed. It is packaged in JEDEC standard 42 - pin plastic SOJ.

Notes : 1. AC measurements assume tT = 5ns. used, a minimum of eight CAS-before-RAS refresh cycles are required.

2. An initial pause of 100 s is required after power up, and it followed by a minimum of eight initialization cycles (RAS-only refresh cycle or CAS-before-RAS refresh cycle). If the internal refresh counter is
3. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. 4. All the V CC and V SS pins shall be supplied with the same voltage. 5. tRAS(min) = t RWD(min) + tRWL (min) + tT in read - modify-write cycle. 6. tCAS(min) = t CWD(min) + tCWL (min) + tT in read - modify-write cycle. 7. tASC(min), tRCS(min), tWCS(min) and tRPC are determined by the falling edge of CAS. 8. t RCD(max) is specified as a reference point only, and tRAC (max) can be met with the tRCD(max) limit. Otherwise, tRAC is controlled exclusively by tCAC if tRCD is greater than the specified t RCD(max) limit. 9. t RAD(max) is specified as a reference point only, and tRAC(max) can be met with the tRAD(max) limit. Otherwise, tRAC is controlled exclusively by tAA if tRAD is greater than the specified tRAD(max) limit. 10. tCRP, tCHR , tRCH, tCPA and tCPW are determined by the rising edge of CAS. 11. V IH(min) and V IL(max) are reference levels for measuring timing or input signals. Therefore, transition time is measured between VIH and VIL. 12. Assumes that t RCD

tRCD(max) and tRAD
tRAD(max). If tRCD or tRAD is greater than the maximum
recommended value shown in this table, tRAC exceeds the value shown. 13. Assumes that tRCD tRCD(max) and tRAD

tRAD(max).
14. Access time is determined by the maximum among tAA, tCAC, tCPA. 15. Assumes that tRCD tRCD(max) and tRAD tRAD(max).
16. Either t RCH or tRRH must be satisfied for a read cycle. 17. tOFF(max) and tOEZ(max) define the time at which the output achieves the open circuit condition ( high impedance). 18. tWCS, tRWD , tCWD, and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS
tWCS (min), the cycle is an early write cycle and the
data output will remain open circuit (high impedance) throughout the entire cycle. If t RWD tRWD(min), tCWD
tCWD(min), t AWD
tAWD(min), and tCPW
tCPW(min), the cycle is a read-modify-write and the
data output will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of the data output (at access time) is indeterminate. 19. These parameters are referenced to CAS in an early write cycle and to WE edge in a delayed write or a read-modify-write cycle. 20. tRASP defines RAS pulse width in Fast page mode cycles.
