Abstract: FIELD: testing. 
     SUBSTANCE: invention relates to the field of testing electronics, in particular, determining the time of operation of a static random-access memory and identifying counterfeit products. Substance: unstable bits are counted by entering, at the nominal power supply voltage (V p  = V nom ), a value of 1 or 0 into all bits of the SRAM. The power supply voltage is then reduced to a value selected from the range  , guaranteed to be below the critical information retention level of the microchip. All bits of the SRAM are then consecutively transferred along the line of words to the reading mode for a period of time, sufficient for discharging the RC constant of the electrical circuit. Then the contents of the SRAM are read and the number of bits with a change in the value thereof (N) is counted. The microchip of the SRAM with a value of 1 or 0 entered in all cells is subjected to stress impact by means of exposure to an elevated temperature and voltage (V stress ) for a period of time Δt. The method is implemented by means of a combination of counting of unstable bits and at least two iterations of stress impact and counting of unstable bits, wherein, after the first count of unstable bits, the initial number of unstable bits N 0 =N is initialised, after the second count of unstable bits, the incremented number of unstable bits is counted relative to the first count of the first iteration of stress ΔN 1 =N-N 0 , after the third count of unstable bits, the total incremented number of unstable bits is counted relative to the second count after ΔN 2 =N-N 0 , then the trueness of the expression   is calculated, the trueness whereof indicates that the SRAM microchip is "new", and a false value indicates that it is "used". 
     EFFECT: identification of used SRAM (static random access memory apparatuses) microchips by simple digital equipment without applying precise analogue measuring tools, by means of the standard interface of the microchip, without special requirements for the electrical and topological layout thereof, without a priori primary information about the properties of the physically unclonable functions thereof.

Abstract: FIELD: medicine.   
     SUBSTANCE” invention relates to medicine, namely ophthalmology. A map of the chorioicapillary layer with the measured area of type I choroidal neovascularization (CNV) is preliminarily obtained, which is superimposed on the map of the superficial vascular plexus and the contour of CNV is outlined by the location of the vessels of the superficial vascular plexus. Then, in the micro-pulse mode, the parameters of the sub-threshold micro-pulse laser exposure (STMPLE) are tested: the spot diameter is 100 microns, the borehole is 4.7%, the pulse exposure is 50 microseconds, the pulse packet duration is 200 ms. The selected power parameters are reduced by 50%. Next, STMPLE is initially carried out along the border of CNV and the detachment of the SNR: the applicates are applied one after another along the border of CNV with the position of each application on    of its area on the zone of CNV and    of the area on the zone of detachment of the sensorineural retina (SNR). In this case, the applications are applied, starting from the upper part of type I HCV, from left to right to the opposite border of the HCV. Then the impact is carried out in the opposite direction to the right border of HCV with the overlap of each subsequent application on   of the area. After that, STMPLE is carried out over the entire area of the type I CNV, while each application is applied with overlap on   of the area of the previous application. Next, STMPLE is carried out in the projection area of the detachment of the SNR over the entire area with the setting of the applicates “joint to joint”. An angiogenesis inhibitor is administered intravitreally on the next day after STMPLE.  
     EFFECT: method provides for more pronounced fibrosis of type I CNV, reducing the risk of recurrence or progression of choroidal neovascularization.
