Semiconductor MSC23236D/DL-xxBS20/DS20
2,097,152-word x 36-bit DYNAMIC RAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The MSC23236D/DL-xxBS20/DS20 is a fully decoded, 2,097,152-word x 36-bit CMOS dynamic random access memory module composed of sixteen 4Mb DRAMs in SOJ packages and four 2Mb DRAMs in SOJ packages mounted with twenty decoupling capacitors on a 72-pin glass epoxy single-inline package. This module supports any application where high density and large capacity of storage memory are required. The MSC23236DL (the lowpower version) is specially designed for lower-power applications.

Notes: 1. A start-up delay of 200s is required after power-up, followed by a minimum of eight initialization cycles (/RAS only refresh or /CAS before /RAS refresh) before proper device operation is achieved. 2. The AC characteristics assumes tT = 5ns. 3. VIH(Min.) and VIL(Max.) are reference levels for measuring input timing signals. Transition time (tT) are measured between VIH and VIL. 4. This parameter is measured with a load circuit equivalent to 2TTL loads and 100pF. 5. Operation within the tRCD(Max.) limit ensures that tRAC(Max.) can be met. tRCD(Max.) is specified as a reference point only. If tRCD is greater than the specified tRCD(Max.) limit, then the access time is controlled by tCAC. 6. Operation within the tRAD(Max.) limit ensures that tRAC(Max.) can be met. tRAD(Max.) is specified as a reference point only. If tRAD is greater than the specified tRAD(Max.) limit, then the access time is controlled by tAA. 7. tOFF(Max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. 8. tRCH or tRRH must be satisfied for a read cycle. 9. The test mode is initiated by performing a /WE and /CAS before /RAS refresh cycle. This mode is latched and remains in effect until the exit cycle is generated. The test mode specified in this data sheet is a 2-bit parallel test function. CA0 is not used. In a read cycle, if all internal bits are equal, the DQ pin will indicate a high level. If any internal bits are not equal, the DQ pin will indicate a low level. The test mode is cleared and the memory device returned to its normal operating state by a /RAS only refresh or /CAS before /RAS refresh cycle. 10. In a test mode read cycle, the value of access time parameters is delayed for 5ns for the specified value. These parameters should be specified in test mode cycle by adding the above value to the specified value in this data sheet.
