HB56A441BR Series
8,388,608-word × 40-bit High Density Dynamic RAM Module
4,194,304-word × 40-bit High Density Dynamic RAM Module
ADE-203-731A (Z)
Rev.1.0
Feb. 20, 1997
Description
The HB56A841BR is a 8M × 40 dynamic RAM module, mounted 20 pieces of 16-Mbit DRAM
(HM5117400) sealed in SOJ package. The HB56A441BR is a 4M × 40 dynamic RAM module, mounted
10 pieces of 16-Mbit DRAM (HM5117400) sealed in SOJ package. An outline of the HB56A841BR,
HB56A441BR is 72-pin single in-line package. Therefore, the HB56A841BR, HB56A441BR make high
density mounting possible without surface mount technology. The HB56A841BR, HB56A441BR provide
common data inputs and outputs. Decoupling capacitors are mounted on the module board.

Notes: 1. AC measurements assume t T = 5 ns.
2. An initial pause of 200 µs is required after power up followed by a minimum of eight initialization
cycles (any combination of cycles containing RAS-only refresh cycle or CAS-before-RAS
refresh). If the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh
cycles are required.
3. Operation with the tRCD (max) limit insures that tRAC (max) can be met, tRCD (max) is specified as a
reference point only; if t RCD is greater than the specified tRCD (max) limit, then access time is
controlled exclusively by tCAC .
4. Operation with the tRAD (max) limit insures that tRAC (max) can be met, tRAD (max) is specified as a
reference point only; if t RAD is greater than the specified tRAD (max) limit, then access time is
controlled exclusively by tAA .
5. Either t OED or tCDD must be satisfied.
6. Either t DZO or tDZC must be satisfied.
7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition
times are measured between V IH (min) and VIL (max).
8. 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, t RAC exceeds the value shown.
9. Measured with a load circuit equivalent to 2TTL loads and 100 pF.
10. Assumes that t RCD ≥ tRCD (max) and tRCD + tCAC (max) ≥ tRAD + tAA (max).
11. Assumes that t RAD ≥ tRAD (max) and tRCD + tCAC (max) ≤ tRAD + tAA (max).
12. Either t RCH or tRRH must be satisfied for a read cycles.
13. t OFF (max) and tOEZ (max) is define the time at which the outputs achieve the open circuit condition
and are not referred to output voltage levels.
14. t WCS , t RWD, t CWD, t CPW and t AWD are not restrictive operating parameters. They are included in the
data sheet as electrical characteristics only; if t WCS ≥ tWCS (min), the cycle is an early write cycle
and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD
≥ tRWD (min), tCWD ≥ tCWD (min), and tAWD ≥ tAWD (min) or tCWD ≥ tCWD (min), tAWD ≥ tAWD (min) and tCPW ≥
t CPW (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 out
(at access time) is indeterminate.
15. These parameters are referred to CAS leading edge in early write cycle and to WE leading edge
in delayed write or read-modify-write cycles.
16. t RASP defines RAS pulse width in fast page mode cycles.
17. Access time is determined by the longest among tAA, t CAC or tCPA.
18. In delayed write or read-modify-write cycle, OE must disable output buffer prior to applying data
to the device. After RAS is reset, if tOEH ≥ tCWL, the DQ pin will remain open circuit (high
impedance); if t OEH ≤ tCWL, invalid data will be out at each DQ.
19. All the V CC and VSS pins shall be supplied with the same voltages.
20. When output buffers are enabled once, sustain the low impedance state until valid data is
obtained. When output buffer is turned on and off within a very short time, generally causes
large V CC / V SS line noise, which causes to degrade V IH min / V IL max level.
21. XXX: H or L (H: VIH (min) ≤ V IN ≤ V IH (max), L: VIL (min) ≤ V IN ≤ V IL (max))
