DESCRIPTION
1 BIT DY
NAMIC RAM
PRELIMINARY
The TC514100AP/AJ/ASJ/AZ is the new generation dynamic RAM organized 4,194,304 words by 1
bit. The Tc514100AP/AJ/ASJ/A2 utilizes TOSHIBA'S CMOS Silicon gate process technology as well as
advanced circuit techniques to provide wide operating margins, both internally and to the system user.
Multiplexed address inputs permit the TC514100AP/AJ/ASJ/AZ to be packaged in a standard 18 pin
plastic DIP, 26/20 pin plastic SOJ (300/350mil) and 20 pin plastic MP. The package size provides high
system bit densities and is compatible with widely available automated testing and insertion
equipment. System oriented features include single power supply of 5Vi10% tolerance, direct
interfacing capability with high performance logic families such as Schottky 'ITL.

NOTES:
1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent
damage to the device.
All voltages are referenced to vss.
ICCI. Icca, ICOS, ICC6 depend on cycle rate.
Icc1, ICC4 depend on output loading. Specified values are obtained with the output open.
Column address can be changed once or less While Ma”, and CKS=VHL
mcnp-mgo
An initial pause of 200ps is required after power-up followed by 8 tITG only refresh cycles before
proper device operation is achieved, In case of using internal refresh counter, a minimum of 8
Wig before RAS refresh cycles instead of 8 PIS only refresh cycles are required.
7. AC measurements assume br=5ns.
8. VI” (min.) and Vit, (max.) are reference levels for measuring timing of input signals. Also,
transition times are measured between Vm and Vu,,
9. Measured with a load equivalent to 2 TIT loads and lOOpF.
10. tom: (max0defines the time at which the output achieves the open circuit condition and is not
referenced to output voltage levels.
11. Either tncu or tmm must be satisfied for a read cycle.
12. These parameters are referenced to TM leading edge in early write cycles and to WRITE leading
edge in Read-Modify-Write cycles.
13. twcs, tRWD, tCWD, tAWD and tcpwp are not restrictive operating parameters. They are included
in the data sheet as electrical characteristics only. If twcsg twcs(min.), the cycle is an early
write cycle and data out pin will remain open circuit (high impedance) throughout the entire cycle;
If tawo2-t tRWDKmin.), tcvmittcwn(min0, tAwD2ttAwn(min.) and tcPwro2ttcPwD(min.) (Fast Page
Mode), the cycle is a Read-Modify-Write cycle and the data out will contain data read from the
selected cell: If neither of the above sets of conditions is satisfied, the condition of the data out(at
access time) is indeterminate.
14. Operation within the tncp(max.) limit insures that tRAC (max.) can be met.
tRcu(max.)is specified as a reference point only: If tncp is greater than the specified tttCD (max.)
limit, then access time is controlled by tCAC.
15. Operation within the tRAD(max.) limit insures that tmc(max.) can be met.
tnm)(max.)is speciried as a reference point only: If tRAD is greater than the specirsed tRAD(max.)
limit, then access time is controlled by tAA.

TEST MODE
The TC514100AP/AJ/ASJ/AZ is the RAM organized 4,194,304 words by 1 bits, it is internally
organized 524,288 words by 8 bits. In "Test Mode", data are written into 8 sectors in parallel and
retrieved the same way. Alon, A100 and A00 are not used. If, upon reading, all bits equal (all"1"s or
"O"s), the data output pin indicates a"I". If any of the bits differed, the data output pin would indicate
a"0". Fig.1 shows the block diagram of TC514100AP/AJ/ASJIAL In 'Test Mode", the 4M DRAM can be
tested as if it were a512K DRAM.
”WRITE, (KS Before m Refresh Cyele"puts the device into "Test Mode". And“m Before m
Refresh Cycle" or "m Only Refresh Cycle"puts it back into "Normal Mode". In the Test Mode,
"WRTT‘E, CTS Before m Refresh Cycle"performs the refresh operation with the internal refresh
address counter. The "Test Mode"function reduces test timesW8 in case of N test pattern).
